Ever since the inception of the Like button, Facebook users have been asking for a "dislike" button. Today, Facebook is testing a "downvote" button with certain users in the comment section of posts within Facebook groups and on old Facebook memories content. The Daily Beast reports: The feature appears to give users the ability to downrank certain comments. This is the first time Facebook has tested anything similar to a "dislike" button and it could theoretically allow for content that's offensive or relevant to be pushed to the bottom of a comment feed. In 2016, citing Facebook executives, Bloomberg said a dislike button "had been rejected on the grounds that it would sow too much negativity" to the platform. It's unclear how widely the dislike button is being tested. Facebook regularly tests features with small subsets of users that never end up rolling out to the broader public. Most users currently are only able to either Like or Reply to comments in a thread. The downvote option could have radical implications on what types of discussions and comments flourish on the platform. While it could theoretically be used to de-rank inflammatory or problematic comments, it could also easily be used as a tool for abuse.
