Sorry to hear you got scammed but, seriously, how could you miss the BIG WARNING MESSAGE in the bright yellow box that appears above his thread when you open it plus the dozen or 2 negative feedbacks posted under his trust. As my grandmother used to say "You can lead a horse to water but you can't make him read the warnings." Unfortunately scammers do not get banned on this forum.
The big warning message is not actually that big at least not for me when I logged out and I always said that the small orange numbers that people who are logged in see are even less noticeable. I somehow doubt the OP doesn't have an older account here and he just used this one as a throwaway one.
Not saying that this isn't 101% his fault but seriously we should bring back the scammer tag or do something more drastic than putting a two-line of text warning, don't understand why theymos is so much against it.
