This was stated by Lauda, but the fact that aTriz has posted multiple ANN/bounty threads subsequent to lauda making this announcement removes credibility from lauda's statement that aTriz was "suspended"

I agree the account was purchased, this is fairly clear.

I don't think aTriz has the private keys to addresses associated with the account from 2013. The reason being is that some of said addresses have had fairly substantial amounts of bitcoin held in them subsequent to the account being transferred. In fact, it appears that new aTriz transferred at least 0.2BTC to old aTriz subsequent to buying the account, which implies that new aTriz may have paid an extortion payment to cover up the fact he bought the account, which although I it is very wrong to extort someone, I find very ironic, considering lauda's involvement.
