Can you provide proof of ownership(sign message from an address used some time ago from the accounts)?
We had a problem recently with an user that used to sell acount in behalf of others, until he ran away with all money.
Is your question pointed at me? If so then yes I am able to do that upon receipt of payment (or if escrow is used, after escrow has been funded).
The OP was saying that he wanted to
buy accounts.
