[X Tests 'Private Downvote' Feature, Nikita Bier Confirms Internal Testing] According to NDTV, social platform X is conducting small-scale testing of a 'dislike' downvote feature. After a user suggested adding a downvote button on X, X's product lead Nikita Bier promptly replied, 'Give me 60 seconds.' Shortly after, some users noticed a new 'thumbs down' icon under posts. The current test primarily targets reply content, with downvote results not publicly displayed but serving as private negative feedback signals. These signals are integrated into the platform's ranking algorithm to adjust content exposure. As early as 2021, X had explored a similar 'downvote' mechanism on iOS to improve reply quality.
