We used to have a STFU button. (Shut The F**K up). Only supposed to be a bit of a laugh but folk took it to heart and got bit upset ahah. Although not as aggressive I think a dislike button would be similar. Folk don’t like having their posts disliked
If it’s of any interest I do have a licence and files for a premium XenForo add-on that allows different reactions. Would at least allow us to have a laugh react etc
