Meta launched a tagable Meta AI account on Threads on May 12, 2026, letting users summon the assistant inside replies for quick answers and conversation context — and immediately drew backlash because the account cannot be blocked. The complaint trended on Threads with more than 1 million posts before disappearing from the trending list, according to Engadget's Karissa Bell.
The feature is live as a test in five countries: Argentina, Malaysia, Mexico, Saudi Arabia, and Singapore. It is the same footprint Meta used for its earlier Threads mention rollout, which AI Chat Daily covered last week. A pinned demo video shows users tagging Meta AI for answers to questions like "why is everyone obsessed with matcha" and "how do you actually pronounce 'Cannes'?"
The mechanic mirrors what xAI's Grok does on X, where users tag the bot mid-thread for instant context. Meta is borrowing the format wholesale, with one significant difference: Grok is an account users can mute or block like any other. Meta AI, by design or by oversight, sits outside that control.
Key facts
- 01Meta announced on May 12, 2026 that Threads users can tag a new Meta AI account for answers and context inside replies.
- 02The Meta AI profile has no block option in its three-dots menu, and users who saw a block toggle reported errors when they tried to use it.
- 03The complaint trended on Threads with more than 1 million posts before vanishing from the trending list.
- 04The feature is in test in Argentina, Malaysia, Mexico, Saudi Arabia, and Singapore — the same five-country footprint Meta used for the Threads mention rollout.
- 05Meta launched its Muse Spark model in April and is pushing it across its apps as it chases OpenAI and Google.
Opening the three-dots menu on the Meta AI profile shows no block option. Some users who did see a block toggle reported errors when they tried to use it. The replies under posts from Meta AI itself, the main Threads account, and Threads chief Connor Hayes filled with users objecting to the lack of an off switch.

Meta spokesperson Christine Pai told The Verge that opt-out controls do exist, just not as a hard block. "Users can manage their Meta AI experience during the test," Pai said. "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 distinction matters. Muting an account hides its posts from a feed but does not stop the account from interacting; blocking severs the relationship entirely. On Threads, where Meta AI can be summoned by anyone tagging it under a post, a non-blockable assistant means the bot can surface inside a user's own replies whether they want it there or not.
The launch sits inside a broader Meta push to catch OpenAI and Google. The company has spent billions on AI hiring this year and shipped Muse Spark, a new model, in April, with plans to fan it across Meta's apps and services. The Threads account is the most visible consumer surface for that strategy so far.
Meta is also betting that the Grok-style tag-the-bot interaction is the format that wins social-AI. On X, the pattern has driven engagement around Grok, and Meta's pinned demo leans into the same use case — quick, in-thread answers without leaving the conversation. Whether it lands depends on whether users want an assistant in their replies at all, and the early Threads response suggests not all of them do.
The disappearance of the "Users cannot block Meta AI" trend from Threads' trending list while related complaints kept posting is the part that will draw the most scrutiny. Bell reported it was trending with over 1 million posts and then was no longer showing for her. Meta has not publicly explained the change, and trending algorithms are not transparent.
What Meta has not said is whether a block option is coming. Pai's statement frames mute, hide, and "Not interested" as the answer, not as a placeholder for stronger controls. That is a product choice, and it tells you how Meta views the Meta AI account: not as another user on the platform, but as a system feature.
For Meta, the calculation is straightforward — every block button is a kill switch on distribution for a product the company is spending billions to push. For users, the calculation is simpler still, which is why the complaint moved a million posts in a day. The pattern to watch is whether Meta walks this back the way platforms usually do when a default lands badly, or whether Meta AI stays a permanent fixture of the Threads experience. The five-country test gives the company room to adjust before a wider rollout, and the next signal will be what the controls look like when the feature leaves test.
