This culture really needs to change. We can start by removing signatures from Newbies and Juniors and punishing ICOs that pay people for this rubbish. Some IPs should probably be either permanently blacklisted as well if they've had colossal abuses from them or maybe the evil fee substantially increased.
I agree with these, seems like banning Newbies and Jr. Members permanently is just a waste of time as these people are still free to create new accounts and losing Newbie and Jr. Member ranked account is not a big problem to them. I will agree more if we make Newbie and Jr. Member ranks completely useless. Remove signatures, can only post 5 or less per day (just a suggestion) and don't allow these ranks to join any bounties. Of course, the account will be useful after reaching Member rank as Signatures will be available again. Making Newbie and Jr. Member rank completely useless will make spammers to give up what they were doing.
