I read it better that time.
I would suggest not bothering kenny with frivolous things like this, I can give you enough of a reply/"help".
It seems all I can say is you screwed up dude. As far as transactions go, if the item was traded to muzza, it was his right to sell it. You lost ownership of it when the user of your account sold it, unless the account was hacked.
If muzza said he'd give it back, it'd be nice, but it was a "out of the goodness of his heart" kinda thing. The item was his, he did not have to trade it back. But beyond just being a **** if he promised it back to you, there's no rule breaking or anything worthy of warning anyone.
The warning here would go to people who lend their accounts out, because the person they lend it to just might get them screwed over. I hope you understand why I originally banned account sharing now.
