Ignoring whether this user is actually a scammer or not, forum people's ratings on account sales are negative and are considered untrustworthy.
And in this case, considering how difficult it is to build a reputation, no one will actually sell an account with a positive trust score if he cares about the forum. The only account I've found that comes close to those specs is
o_solo_miner (
BPIP:most merit). And yeah, this offer comes from newbies who incidentally are all scammers, impersonators.
As I recall selling accounts is not frowned upon and will only invite DT for negative tags so mentioning the special features of the accounts being sold is no longer done by them. I might agree that this is a scammer's attempt to convince potential buyers, but sadly it's nothing out of the ordinary.
He could be selling fake accounts that might not be his, so I don't think it's not true to tag the accounts that closely match the traits listed unless there is suspicious activity on the account.
