Ebay, refund, I doubt it.....
I think you may have made an error by thinking that a big corporation has to abide by the same laws as us lowly consumers.
I would have thought they would wriggle out of it by claiming that they do not take a percentage of the sale itself, but make a charge for their services based on the value of the item. If they where literarly taking x percent from a paypal transaction, then I guess they would be profiting directly from crime.
Personally I prefer to buy my stolen goods from a Pete Docherty look-a-like in the pub, he did say he could could get "anyfink you wan't geezer" but I'm not sure he meant factory management software...
