What's morally wrong of Garr's actions is the decision to keep this price manipulator anonymous. Had he revealed the existence and admitted to the use of the account before beginning the "auction", his actions would be completely free of any moral fault.
In other words, if he shilled from his own account (why bother with establishing an alt if everyone knows it's you?), everything would be fine, yeah. Lulzy, 'coz no one would be stupid enough to think of the charade as an auction, but ethically wrong? No.
