That could be true but it does not mean over all it is net positive. You have to take into account the innocent accounts destroyed in this and the fall out from that ie the forum is getting a hostile environment and it will only get worse while persons are using red tags for anything other than scams or direct scammers. The possible implications for free speech.
nobody is violating your rights of free speech just because you got a red tag,
you are doing more speech than most other members.
joining signature campaign or trading on the forum is what the negative tags you got " which i again say that you shouldn't get" - affects you most.
