I had a guy from Poland bid on my auctions once to the tune of about $60 and then I couldn't get payment from him. Mike L told me to block him from ever bidding again so I did. About a month later I get another guy from Poland, with a different username, bidding on my auctions. Guess what, it was the same guy. This time he did pay though. I informed Mike L about this guy with another username and he was surprised and said he would look into it. I didn't hear any more about him from Mike.
