Meta is testing a new feature on Threads that lets users tag the company's official Meta AI account to get answers to questions or context about conversations—but there's one big problem. Users quickly discovered they cannot block the Meta AI profile, and the internet isn't happy about it. The feature works similarly to how X users can tag xAI's Grok bot into replies. On Threads, tagging @MetaAI lets you ask burning questions like "why is everyone obsessed with matcha" or "how do you actually pronounce 'Cannes'?" The test launched this week in Argentina, Malaysia, Mexico, Saudi Arabia, and Singapore, according to reports from Engadget and The Verge. But here's where things get sketchy for power users who value platform autonomy. If you navigate to the three-dot menu on Meta's AI profile, there's no block option—something that's standard on virtually every other account type. Users who reported seeing the blocking option hit errors when they tried to use it. The hashtag "Users cannot block Meta AI" briefly trended with over one million posts before mysteriously disappearing from trending topics entirely. Meta spokesperson Christine Pai provided a statement to The Verge: "Users can manage their Meta AI experience during the test. We want to give people a way to quickly gather context before jumping into the conversation, but if you want to see fewer Meta AI replies in your Threads feed you can mute or hide Meta AI replies, or use the 'Not interested' option on any Meta AI post." The company is positioning muting as an alternative to blocking, but that's not quite the same thing—muting doesn't prevent an account from existing and potentially interacting with your content.

Why This Matters for Platform Autonomy

The inability to block a corporate AI account raises legitimate questions about user control. Blocking exists on social platforms because users should have agency over their digital spaces—who can interact with them, who shows up in their feeds, who's allowed near their conversations. When a company removes that option from its own promotional account, it sets a concerning precedent. What's next—mandatory follows for Meta AI? Meta has been investing heavily in AI as it races to catch competitors like OpenAI and Google, reportedly spending billions on AI talent acquisition. The company launched its Muse Spark model in April 2026, promising to bring the technology across its app ecosystem. Threads represents a key battleground for user attention, and Meta clearly wants its AI front and center—even if users would prefer otherwise.

Key Takeaways

  • Meta is testing an @MetaAI tagging feature on Threads in five countries: Argentina, Malaysia, Mexico, Saudi Arabia, and Singapore
  • Users cannot block the Meta AI account and report errors when attempting to do so
  • "Users cannot block Meta AI" trended with 1M+ posts before disappearing from trending topics
  • Meta's suggested workaround is muting rather than blocking—but these are not equivalent solutions

The Bottom Line

Meta's framing of this as a "test" doesn't excuse stripping away user control. Muting an account you can't block isn't a feature—it's a consolation prize. If Big Tech wants AI everywhere, they need to accept that users should still get to choose whether their AI shows up in their mentions. Platform autonomy isn't optional.
