A mean to downvote posts and have post with say "-5" show as hidden/collapsed by everyone with a hide trigger of >-5
Sorry but these suggestions are retarded.
Moderators and not random users should delete posts and ban people! Why the hell should anyone message disappear because "some users" clicked ignore button? So long for discussions, either you are ok with what the other people say or then they downvote you and your message disappear, no matter if it follow every rules and is fine? That would sucks!
Especially in this forum, we have people with tons of different opinions. Who disagree of course will happily downvote a message. But why should it disappear? Because someone don't like it? Meh
