Most sellers on eBay are fully aware that the players they sell are hacked. They changed IDs often and build up good feedback selling small things. They then move on to hacked players and are able to sell quite a few before the negative feedback catches up with them. From prior experience, the sellers I've bought hacked players from are definitely aware of what they've sold and have tried to cover it up.
