Don't tell me you actually believe this 'sharing an account' bollocks. It's as old as saying 'it was my sibling!' when you've done something wrong and don't want to take responsibility for it.
No, I'm pretty sure they are sharing accounts. He isn't trying to save face because he is acting just as dumb both ways and not defending himself at all.
In my opinion, their account should be banned because nothing they post even makes sense.
