This forum is full of scammers, you know this very well but it looks like you're not interested in stopping them.
One of the ways to make scammers harder to scam someone else is to provide the evidence so DT members like me can tag the user, but how can I (or any other DT member) do that if you don't provide any evidence for your claims? Just by saying "I've been scammed"?
Oh, you say "chances are that he ends up getting tagged and flagged which might save someone else from losing money": tagged and flagged?? In any serious forum a scammer is banned, not flagged!
Scams are not moderated on this forum, as simple as that. And if you wanted to be safe, you should have used escrow.
