Just food for thought: It seems to me that trouble makers (spammers, trollers, fighters) on the forum all have a very similar characteristic. If you look at their profile you will generally find that they have very minimal stats. Generally something like Gender - Yes. and NOTHING else. Perhaps REQUIRING a member to put forth a little effort and create a profile before posting ANYTHING would actually give them more of a tie to the site and discourage spamming, trolling, fighting, etc.
