Meta is testing a Threads feature that lets users tag Meta AI for answers, but users cannot block the account.

Meta announced on Tuesday that it's testing a Threads feature letting users tag a Meta AI account to get answers to questions or context about conversations. The feature is initially available as a test in Argentina, Malaysia, Mexico, Saudi Arabia, and Singapore.

Users discovered that the Meta AI account cannot be blocked like other accounts. Meta spokesperson Christine Pai said users can instead mute or hide Meta AI replies, or use the 'Not interested' option on Meta AI posts to manage their experience during the test.

Threads users posted angry replies to Meta AI and Threads leadership about the inability to block the account. 'Users cannot block Meta AI' was reported as a trending topic on Threads with more than one million posts, though the trend is no longer visible.
