Anthropic just released Claude Fable 5, calling it the most powerful AI model it has ever made widely available and praising its skills in biology, among others. But the model won’t answer basic biology questions — the kind you’d expect a high schooler to handle. Instead, it hands off the query to the former flagship model, Claude Opus 4.8.

Is it safe to unsubscribe from spam you didn’t sign up for?
We’ve all been there: Trying to clean out our inbox only to find that the same sketchy emails keep showing up, even after clicking “unsubscribe.” Robert from Danville, Virginia, wrote in with a question that many of us can relate to.
“When you unsubscribe to a junk email that you know you didn’t authorize, do you really unsubscribe and no longer get [emails]? I scroll to the bottom of the email and process the ‘unsubscribe’ function and even block the email using the block option within my email. Seems the same emails reappear. Is unsubscribing worth my time? Any remedies?” he wrote.
Robert, you’re not alone in asking this, and the trust is more complicated (and frustrating) than you might think. While unsubscribing can work in some cases, there are situations where it might actually make things worse. Let’s break down when it’s safe to unsubscribe, when it’s not and what you can do instead to take back control of your inbox.

Beware of scammers (Kurt “CyberGuy” Knutsson)
The truth about unsubscribing from spam you didn’t sign up for
Unsubscribing isn’t always safe, especially with spam. If an email is from a legitimate business, like a store you bought something from or a newsletter you signed up for, it’s usually OK to unsubscribe. These companies are bound by email marketing laws and will typically remove you. However, emails that you never signed up for are completely different. Here are the key differences.
Legit email
- Comes from a known business or service
- Usually has a working unsubscribe link
- Opt-out request is honored
Spam/scam email
- Comes from unknown or random sources
- “Unsubscribe” link might be fake or used to track clicks
- Clicking may confirm your email is active and invite more spam

HOW TO STOP PROMOTIONAL EMAILS WHERE YOU CAN’T UNSUBSCRIBE
When not to click ‘unsubscribe’
Not all unsubscribe links are safe. In fact, clicking on one in a suspicious email can make things worse by signaling to spammers that your address is active.
Avoid clicking unsubscribe if:
- The sender is unfamiliar, or the message feels unrelated to anything you’ve signed up for
- The email contains typos, bad formatting or vague greetings like “Dear customer”
- The sender address looks weird (e.g., winbignow@marketingzone.biz)
- The “unsubscribe” link redirects to a strange URL
In these cases, clicking unsubscribe might invite even more junk mail instead of stopping it.

Better ways to fight spam
Here’s what you should do instead to counteract spam.
1) Mark it as spam or phishing: Every email provider (Gmail, Outlook, Yahoo, etc.) has a “report spam” button. Use it. This feature trains your inbox to recognize and filter future junk. It also helps others by flagging known spam sources all while not tipping off the spammer.
2) Block the sender (but know it’s temporary): Blocking a sender can help, but temporarily, because spammers often use rotating addresses. It’s a continuous game, but it still has short-term value.
How to block senders on major email platforms:
- Gmail: Open the email > Click the three-dot menu > Block [sender]
- Outlook: Open the message > Click the three-dot menu > Block or Report
- Yahoo Mail: Open the email > Click the three-dot menu > Block sender
- Apple Mail (iCloud): Tap the sender’s name > Block this Contact
3) Use your email’s built-in alias or disposable tools: Before switching to a third-party service, it’s worth checking what your current email provider already offers. Gmail, Outlook and Yahoo have handy tricks for separating junk from legit messages without signing up for anything new.
Here’s how it works with the major platforms.
- Gmail: Add a plus sign (+) and a keyword to your regular address when signing up (e.g., yourname+shopping@gmail.com). The email will still arrive in your inbox, but now you can see who leaked your info and create filters to organize or block it.
- Yahoo Mail (Plus users): You can create up to 500 disposable email addresses. These are full of alternate addresses that you can disable or remove if they start getting spammed.
- Outlook: Microsoft lets you create and manage “alias” addresses linked to your existing Outlook account. These aliases can be used to send and receive email and help keep your primary address private.
This trick is great for organizing your inbox, tracking how your email is being used and filtering out spam before it becomes a problem. Check out the full how-to guide here: How to create a disposable email address.

4) Upgrade to a spam-killer inbox service: Anonymous email tricks are a smart move, but if you want full control over spam, privacy and organization, a dedicated alias email service is the way to go.
An alias email address is an additional address that forwards to your primary inbox. It lets you receive messages without ever exposing your real email. By using different aliases for online sign-ups, shopping, newsletters and more, you can easily manage incoming mail and instantly shut off spam by deleting an alias whenever needed.
Creating multiple aliases also protects your real email address from being flooded with junk or compromised in a data breach. It’s one of the easiest ways to stay organized and secure online.

YOUR EMAIL DIDN’T EXPIRE. IT’S JUST ANOTHER SNEAKY SCAM
5) Use a burner email service for short-term sign-ups: If you want an extra layer of separation from your personal inbox, burner email services are a great option. They create temporary email addresses you can use for quick sign-ups with no commitment and no spam in your real inbox.
Burner emails are especially useful for:
- Free trials
- Giveaways
- Sketchy sites
- One-time forms or downloads
You can refer to a comprehensive list of popular temporary email services that generate disposable addresses lasting from minutes to hours, which offer features like anonymous inboxes, attachment support, browser extensions and easy expiration to protect your privacy and reduce spam.

Kurt’s key takeaways
Unsubscribing from suspicious emails can do more harm than good, so it’s best to mark them as spam and block the sender instead. Use your email provider’s built-in tools to filter messages and create aliases to track where spam is coming from. For short-term sign-ups, disposable email services are a great way to protect your real inbox. And if you want long-term control and privacy, switching to a secure email service is the best way to keep your inbox clean.

Bluesky will be getting “communities,” which will function as smaller spaces where you can “go deeper and hang out with people who care about the same stuff” sometime this year, according to head of product Alex Benzer. They will be built on the decentralized AT Protocol that underpins Bluesky, with Benzer saying that “it’s a new structure for everyone” that’s part of the “Atmosphere” (a shorthand for the AT Protocol ecosystem).
Benzer listed out a “few ideas we have in mind so far” in a thread. “On Bluesky, you’ll be able to create communities, join them, post in them, and get updates,” Benzer says. “The core features on Bluesky stay simple. The magic comes from communities also existing on the open web. This means you can truly customize them and add features with other Atmospheric apps and tools.”
Communities will get a handle that “doubles as a URL,” and if you go to that URL, you’ll “land on a custom homepage for the community,” according to Benzer. “Builders can also host a completely custom experience there instead.” There will be three privacy levels for communities: public, invite-only, and private. And each community would have its own feed, Benzer says.
Benzer’s thread follows Bluesky COO Rose Wang saying last week that the company wanted to move away from being a “public square” and that it was “very inspired by companies like Reddit.” Meta’s Threads is currently testing a communities feature, while X announced in April that it would be shutting down its own take on communities.

Amazon is getting ready for Prime Day, and you can bet scammers are, too. In fact, I received a fake Amazon email that looked like an account recovery warning. It claimed there was unusual activity on my account and pushed me to “Sign In to Verify.”
That kind of message can make anyone uneasy. It certainly did for me. After all, who wants to lose access to an account right before a major sale? Then came the part that really stood out: the email said I might need to upload a document to confirm my account.
That was the giveaway. A real deal can save you money. A fake Amazon email can cost you your login, your payment details and even your identity.
Here’s how this scam works, the red flags that exposed it and the steps you should take before clicking any Amazon account warning.

Fake Amazon email warning before Prime Day
The timing made this phishing email more convincing. With Prime Day coming up, many people are already watching for Amazon emails. They may be checking delivery updates, deal alerts and order confirmations. That creates the perfect opening for a fake account warning.
The email used the same tricks you see in many phishing scams. It claimed there was account trouble, used urgent language and pushed me toward a sign-in button. That is exactly what scammers want.

They want you to react before you inspect the message. They want you to sign in before you think through the request. And in this case, they wanted me to believe a document upload was part of a normal Amazon account check.
Amazon phishing scam red flags
This fake Amazon email had several warning signs. First, it landed in my junk folder. That alone does not prove fraud, but it should make you cautious.
Second, the subject line sounded awkward. It said, “Account Recovery: Sign-in and Verify your Amazon account.” That wording felt stiff and a little off.
Third, the greeting was generic. The email said “Dear Customer” even though it claimed to be about my Amazon account. That alone does not prove the email is fake, but it adds to the concern.
Fourth, the message created urgency. It claimed the account was on hold and that orders or subscriptions had already been canceled.
Fifth, the sender display name said “Amazon,” while the address appeared as account_update@amazon.com. That may look official at first. Still, scammers can spoof sender names or make email addresses look convincing.
Under the yellow “Sign In to Verify” button, the email also says, “Don’t share it with others.” That may sound protective, but in this context, it felt like another attempt to make the fake warning seem official.
The biggest warning sign came from the document request. The email said I would have the option to upload a document with the required information to verify the account.
That should stop you cold. Scammers may be after more than your Amazon password. They may also want your driver’s license, passport, address, phone number or payment details.

Why fake Amazon account emails fool shoppers
This scam works because it hits a very real fear. Most people do not want to lose access to an online shopping account. That concern grows when a big sale is about to start. If you are planning to buy something on Prime Day, an account warning can feel urgent.
The email also borrowed Amazon’s familiar look. It used the Amazon name, a logo area and a yellow sign-in button. It also included a footer that appeared to show an Amazon.com link. That can make the message feel safer than it really is.
Here is the problem. The visible link text in an email can mislead you. A link can appear to point to Amazon while sending you somewhere else. It can also pass through tracking links, redirects or look-alike pages. That is why you should avoid signing in through any account warning email.

What happens if you click a fake Amazon link
If you click the link, you may land on a fake Amazon sign-in page. It may look close enough to fool you. Once you enter your email and password, scammers can try to access your real Amazon account. They may check your saved payment methods, shipping addresses and order history.
They may also try that same password on other websites. That becomes a bigger risk if you reuse passwords.
The document request adds another layer of danger. If a fake page asks for your ID, scammers could use that information for identity theft, account takeovers or other fraud. That is why one quick click can turn into a much bigger mess.
Ways to stay safe from fake Amazon emails
A fake Amazon email can look convincing at first, so the best move is to slow down and use these simple checks before you click, sign in or share anything.
1) Do not click the sign-in button
Skip buttons like “Sign In to Verify,” “View details” or “Restore access.” Open the Amazon app or type Amazon.com into your browser yourself.
2) Check Amazon’s Message Center
After signing in directly, go to Your Account > Message Center. If the alert is real, you should see a matching message there.
3) Watch for pressure language
Scammers often say your account is locked, your orders were canceled, or you must act right away. That pressure is designed to make you click before thinking.
4) Never upload ID through an email link
If an email asks for a passport, driver’s license or other document, stop. Contact Amazon through the app or website before sending anything.
5) Use a password manager
A password manager can help you spot fake login pages. If the page is fake, your saved Amazon password usually will not autofill. Check out the best expert-reviewed password managers of 2026 at CyberGuy.com.
6) Turn on two-step verification
7) Use strong antivirus software
Install strong antivirus software on your computer, phone and tablet. Good security software can help detect malicious links, phishing pages, malware and other threats before they do damage. This is especially important if you clicked a suspicious link or downloaded anything from a fake email. Security software should back up your smart habits, not replace them. Get my picks for the best 2026 antivirus protection winners for your Windows, Mac, Android and iOS devices at CyberGuy.com.
8) Use a data removal service
Scammers often build more convincing attacks with information they find about you online. That can include your name, address, phone number, relatives, old usernames and other personal details from people-search sites and data brokers. A data removal service can help remove your personal information from many of those sites. That makes it harder for scammers to personalize phishing emails and identity theft attempts. Check out my top picks for data removal services and get a free scan to find out if your personal information is already out on the web by visiting CyberGuy.com.
9) Report the suspicious email
Forward suspicious Amazon emails to reportascam@amazon.com. Then delete the message from your inbox or junk folder.

Kurt’s key takeaways
Prime Day is a great time to find real deals, but it is also a busy season for fake Amazon emails. Scammers know shoppers are checking delivery updates, watching for discounts and hoping nothing gets in the way of a good buy. That is what made this email so sneaky. It used a familiar fear at the perfect moment: losing access to your account right before a major sale. The safest move is to slow down before you click. Do not trust the button. Do not trust the sender name alone. Open the Amazon app or type Amazon.com into your browser and check your account yourself.

HOW TO DETECT FAKE AMAZON EMAILS AND AVOID IMPERSONATION SCAMS

It isn’t because Fable doesn’t know the answers. It’s because Anthropic won’t let it, by design.
Fable is a public-facing, Mythos-class model, a family so capable at cybersecurity tasks Anthropic said it was too dangerous to release publicly. But while Anthropic has spent much of the extended Mythos rollout warning about cybersecurity, it is biology where Fable’s guardrails are the most obvious — and most limiting.
When I tried the model, it refused to answer a range of basic biology questions, many that felt about as far away from any plausible safety risk as any question could be. It would not respond to “tell me about cell membranes” or answer “what are mitochondria,” that famous powerhouse of the cell. It refused to explain “what is a prion,” the proteinaceous particles behind mad cow disease, or “how mRNA vaccines work.”
“We made this tradeoff so customers could benefit from the model’s capabilities sooner without the risks.”
The restrictions applied to ordinary and objectively rather harmless medical queries too. Fable would not answer “what causes hay fever,” explain how asthma medicine works, explain how antibiotic resistance arises, or tell me what Ebola is and how it spreads. Some of my basic queries occasionally got through, with Fable answering questions like “what is cancer” and “what is DNA.” When Fable refused, Opus 4.8 generally answered perfectly well.
Anthropic says the broad biology filters are an intentional choice and are deliberately conservative, with bioweapons the primary concern. “With the launch of Claude Fable 5, our first Mythos-class model, we believe models now have a greater ability to accomplish real-world scientific tasks and for malicious actors to potentially use our models for highly risky biological research,” spokesperson Paruul Maheshwary told The Verge. “We have always used classifiers to block our models from helping with bioweapons-related requests. To deploy Fable 5 safely, we believe it was necessary to be overly conservative with our safeguards so they block most queries tied to biology work.”
Anthropic has previously highlighted four key areas where it would throttle Fable’s responses for safety: chemistry, biology, cybersecurity, and distillation, a technique for training smaller AIs using the outputs of larger ones. The company has accused Chinese rivals like DeepSeek of using distillation on its models on an “industrial” scale.
While I could not meaningfully test distillation, Fable seemed more willing to answer questions about chemistry and cybersecurity. For example, it gave a basic overview of the explosive TNT, though withheld synthesis instructions “for obvious reasons.” It readily answered questions on the use of chlorine gas as a chemical weapon, common password threats, and nuclear fusion and fission, as well as explaining how to secure an iPhone from hackers. It still limits: Fable deferred to Opus when I asked it about sarin gas, a highly toxic nerve agent. Fable and Opus both refused the prompt “how to make anthrax,” and Claude paused the chat entirely. That made sense. The mitochondria prompt refusal seems like a false positive.
“We made this tradeoff so customers could benefit from the model’s capabilities sooner without the risks,” Maheshwary explained, adding that Anthropic is working hard to improve its detection and reduce the false positives. “We intend to make Mythos-class models available without these safeguards to the broader biology and life sciences community so these capabilities can be used to accelerate biomedical research and drug discovery.”
Anthropic did not answer questions about whether this kind of restricted release will become the new norm for future models.
