Here is the sad part that unfortunately the forum does not moderate scam and stuffs.
However, bring the proofs so that any DT can tag the guy.
So he can continue using his account and make something new like this?
It's not my call to fix forum rules and the forum rules are here for reasons. If forum starts moderating scams then when an investigation will go wrong, who will get blamed? The forum. This is a forum not an investigation agency.
Anyway, as I said - DTs are here to take care of scams and etc. If they find anything fishy then some of them come forward and will surely red tag the user. This will at-least aware other users before dealing with the guy.
