Dislike Button Removed
The old forums had the dislike button which did not exactly do what was intended. The old dislike button was originally intended for posts that were primarily troll posts (eventually hiding them). However, the dislike button was often used to mark a post that the person simply disliked for whatever reason.
Seems to indicate that the dislike button was indeed not for indicating disagreement but rather marking troll posts. Using it to indicate disagreement was an incorrect method for its use.
I get it. It says “Dislike”. Why in the world would it so unambiguously say “Dislike” if you were not meant to use it for that very reason. But there you go. The intent was not that you would use it to simply dislike a post.
That’s why it got removed. So you would have to use your words.
