he is now a proven fraudster, the ban certainly won't stop him to create a new account and starting all over again. that is the expected scenario. I even think he has already made a new account because of many neg tags on his current.
If truly the forum does not care or give a damn on how criminals like this on this forum can be caught and prosecuted, then I must sincerely say that this is a big minus on this forum and it's founders as this shows the forum doesn't really care about its users, and the sad story is that a scammer(knowing that all he or she gets is just a red or negative trust after scamming members here) won't hesitate or think twice before carry out his or her evil act.
He or she scams with an account,
Gets a red or negative trust,
Forgets about that account,
Creates a new account (even from the same ip since no one cares)
Repeats the same thing, and keep it going for as long as he or she can.
I really think that this should be looked into @Theymos (if ever you get to see this).
