I can hear it now.
"I am lowprices of the e-borg. Prepare to be auctioned, I mean assimilated."
I was sorry to hear about your bad luck. Hopefully ebay can get it straightened out so you can get back on it. It is not fair to you to be banned if you were playing by the rules, which it sounds like you were.
I hope they find a way to ban these people who put up all of these fake tractor auctions. I almost bit on one myself, well a couple, but then I remember the old axiom, "If it sounds too good to be true, then it is."
