X is testing a dislike button for replies. The feature is currently rolling out to a limited number of users, so most people may not see it yet.
The dislike option is only available on replies and not on main posts. Also, the count is not visible to others. This makes it clear that the feature is not meant to show public reactions, but to collect feedback in the background.
When someone hits the dislike button, it asks users to tell what was wrong with the reply. One can report the comment as incorrect, AI-generated, Spam, or just selected Not interested in this post.
It seems the feature will be used to evaluate how replies are ranked. At present, replies are often sorted based on likes and early engagement. This system can be easily influenced, which is why irrelevant or spam replies sometimes appear at the top.
With a dislike signal, X can better understand which replies users do not find useful. This can help push down low-quality content and surface better replies. If implemented properly, it can improve the overall experience, especially on popular posts.
There are still some concerns. Dislike signals can be misused by groups to target certain replies or opinions. Even without public counts, this can affect visibility. X will need to balance this signal carefully with other engagement metrics.
This move also shows that X is still trying to fix one of its biggest problems, which is the quality of replies. Likes alone do not give a complete picture, and adding a negative signal can help improve ranking decisions.
