mike_cesara: dtgreene is right, we have some low reputation regular users and high reputation scammers..
Edward_Carnby: Oh, thanks.
I had no clue about that .
I remove rep requirements from the rules list.
But if you see any scammers entered - please - tell me about that. =)
A good way to check for scammers is to do a quick forum search to see if that particular user has been active elsewhere. There are also several threads dedicated to finding and uncovering users that employ alternate accounts for entering give aways. If you think a particular user might be a scammer, just ask around. There are a lot of forum regulars that can usually identify when a poster is really a scammer.
Best of luck!
*edit: That being said, a lot of folks have a quiet forum presence, so... I guess just use your best judgement too!
