Good luck with that appeals process. My experience has been that the eBay "handlers" have at least as high a percentage of idiots as the buyers, if not higher. And the ones who aren't idiots have their hands tied by the same stupid policies favoring the buyer that started the whole thing.
If you're lucky, you can get them to remove a negative feedback comment or a string of low star scores. If it's something that is going to cost eBay money to reverse, fuggeddaboutit
