Ebay used to give the address and phone number of a
person if you asked. The deal was that if they sent
it to you, then YOUR information got sent to THEM.
I don't think they do it anymore. A guy stiffed me
on an auction once and I had already sent him the
money so I got his number and called him! I think
it scared the crap out of him. He couldn't figure
out how I got his info.
