Stellar69 has yet to provide any valid proof. I wouldn't trust any of his claims against OP after so many proofs were provided by him.
And actually...
He implies that if an account has been sold then he will not recover the account back to the previous owner if he can tell that it was sold.
It's been said by mods that accounts will be recovered regardless. That's why buying accounts is always risky for the buyer. because if the seller has used an address in a PM, he'll be able to claim the account's ownership at any time.
This is not true. Theymos has said that he will only potentially recover an account to the rightful owner.

http://www.reddit.com/r/Bitcoin/comments/2hne0g/useraccounts_bitcointalkorg_not_like_other/Account recoveries are my lowest priority because they involve a ton of investigation, and you shouldn't lose your account in the first place. If my investigation is not thorough, I could end up accidentally "recovering" an account by giving it to a thief. But I don't often have hours of spare time to devote to such things, so I end up doing only a few account recoveries per month, and many requests get ignored. (I choose recent requests that look straightforward. For any forum business, if I ignored your past requests, resend it every couple of weeks and make it more clear/straightforward.)
This case is one that I have looked at previously. It has a 7-page thread. It's clear that the OP owned the account at one point. But there's a decent chance that the current owner bought the account from the original owner. Since the case is uncertain, I'm erring on the side of inaction for now.
If you sell an account and it is apparent that the account has been sold to theymos (the only person who is willing/able to recover accounts) then the seller will not be able to recover the account.
Regardless of what the mods say (I haven't even seen them say this and you did not post a link/quote so I would dispute they have even said this) they are not the ones who process these requests nor do they make the decision to recover an account or not.
