Crazy.
I frequently browse Slickdeals.net, and have 200ish posts there.
I had a guy sell me his 360 shortly after launch... he sent me the 360 to let me make sure his offer was legit (was $500 for a premium and COD2). I hadn't paid for it or anything and was floored that he trusted me, as we weren't otherwise acquainted other than his post about the 360 and his own brief posting history.
His response was 'if you cant trust someone here, who can you trust. it's gotta start somewhere' or something similar.
360 worked, i paypaled him the money the next day.
Sorry for those scammed. I've worked in the fraud department of a large-ish .com, can be rough sometimes. Nice job staff of getting the info together, it's often easy to find when you know where to look, and many don't realize their options once they have it.
