Today my forum has a problem with spammers and a couple problem users. They are registering and then they are sending PMs to users with spam or vulgar messages. It is a problem that is hard to prevent because they do it off-hours. So is there an addon that will disable the Conversations function to users with less than 5 forum posts? Also, is there a way to require approval for new member posts? I.e. the first 3 posts. Please advise.
