The only legal transaction that could happen on something like that is the actual creator selling it to somebody and only if the creator didn't upload it to a server already. So pretty much commissions for a "custom" head. I'm sure there's going to be a lot of questionable transactions if this ever comes to fruition. Scumbags eager to take a page from the bread man and sucker these kids for their lunch money.
Maybe graal should do a taylorrichards version of custom uploads. A place where players can find heads and bodies so they can upload them.
