The last time I got screwed a seller sent me a bunch of soccer jerseys (I collect)and they were not up to par. I sent them back since He was a power seller. Well he said he would return my money except he never did. He stoped returning money and emails and the negative feedback started sky rocketing. But he kept on selling! and Ebay didn't do squat.
So I took matters into my own hands and followed all of his auctions and emailed everyone of his bidders that he was not going to send them any merchandise and that he was a crook. I did this for two weeks (I can be tenacious) I made sure to CC him on each email. He promptly returned my money without an email requesting me to stop.

If this guy is still selling on ebay start harrasing his bidders.
Even though you didn't technically go through ebay.
