IMO the meat grinder of scams and trust conflicts has been a large source of these issues. I know a lot of really good people this community could have used that just bailed because they got tired of being at the mercy of bored little OCD children with police hats running around often inventing crimes where there was none, punishing rivals, selectively enforcing, and just general childish control seeking behavior. If you have a community where some idiot can take your ability to trade on a whim, that doesn't exactly foster an environment people want to dedicate much time to, and just breeds general contempt.
