Im not saying that this is certainly the case, but the details you've provided don't explain the quality of the account. The posts might all be 'one-liners' of complete junk in Off-Topic etc and there is no join date.
These facts may help you sell your account quicker, good luck the price is very good for member
I'm only giving that information to serious buyers. The account is fine and has sold many things with no negative rep.
