Eh, how do we know he really owns those accounts?  This could be a sly little revenge scheme here, though I really don't know what to make of it.

If he really does own accounts that are several years old and is just now asking a question like this, my guess is that he bought those older accounts.  Wouldn't surprise me in the least, nor that he got at least one of them banned.  But I'd be careful tagging the accounts he listed in the OP, because who knows if he controls them.
