BadBear had previously dealt with this thread. I don't see any reason why both BadBear and theymos would need to address this thread. They have the same "mod ranking" so what BadBear says should be just as good as something that Theymos says
I would suggest that there is more evidence that the original owner sold then account then there is evidence that the account was not sold. If there was only a small amount of evidence the account was hacked then the account would likely have been recovered (especially considering how good bayuo is at getting attention). He also said that the reason most accounts are hacked/lost is because of "user error". There was recently an "attack" when several phishing PMs were sent in which a link to a "post" was sent with the bitcointalk.org domain but with one of the "i"'s being replaced with a "l". There have been several reports of accounts being hacked since this "attack" and it appears that few/none of these were actually returned. (I would also not be surprised if bayuo was behind this attack in an attempt to either recover his old account or to wreck additional havoc on the forum, or to create additional attention towards the lack of the ability to get accounts recovered - although this is speculation - I reach this conclusion because of bayuo's apparent lack of morals, as he has reneged on his work at least once [when he offered to buy back the account at the purchase price and then backed out] and the evidence that he did in fact sell his account and is now trying to recover it). I would be curious if the zedicus account received a PM from this attack

EDIT: One example of how bayuo is able to get a lot of attention is the fact that this thread has received more views then the sticky thread about how to recover hacked/forgotten password accounts
