15 yr old kids, dont try and hack into paypal accounts and sell non existant items to unsuspecting people and ask them to pay for them with western union credit transfers.
As far as i can see, it appears that all those scam ebay spams you've been getting where the email address of the sender is normal, is somebody who has been hacked and emails sent through them, using their eBay user name etc to make it seem more real.
This is whats happened here. One guy claims to have lost $1100 in my email address debarkle, but seeing as he says "dont worry about it, their just the kicks", hes either madly rich, or hes lying.
