And how many of those scammers were then voted down once they had been exposed? If they are suddenly reemerging as DT2 now it can only mean that no one back then took any action against the scammers, or by contacting CITM to advise them they had scammers in their DT list.
The problem was more so that CITM added many people to his trust list who were not invested in the forum. The people on his trust list were more likely to leave the forum, sell their account, or get their account hacked due to long term inactivity.
