I also think it's rare that any accounts get recovered by theymos nowadays so there's not much chance of someone doing this or it's certainly not as easy as that, but buyers should be aware of the risks and if something goes wrong the staff aren't here to dig you out of it.
You are again going about it the wrong way, and I had explained this earlier. Theymos has a problem recovering as since account trading is allowed, he has to find out whether the account was sold or hacked. If it is not allowed then it becomes very easy; prove that the account belonged to you and it goes back to you.
