Facebook’s idea back in 2016 of rolling out the reaction button instead of a dislike button was very successful as the latter would believe to be a very negative approach.
While trying to keep spammers and abusers away and make things positive and constructive Facebook is working on a "Downvote Button" to report a comment that is inappropriate, uncivil, or misleading.
This feature that would appear below the comments section separately from the reactions button. See below how it looks.
It also make the reporting method a lot easier than the current method, simply click on the downvote button and you will see reporting options like “Offensive - Misleading - Off Topic”.
Currently this feature is only running for a limited number of users in the United States only and upon positive feed backs we might see this feature roll out for everyone worldwide.
