Well, let's say it like this: You make an alt only for scamming art. You stole it, sell it on this alt, make some tc (i mean like over 200k or more) and then from this alt all tc are send to the main. A market squad in this case can check the alt account trade history and see to which user tc were send. But he can't ban the main account because the scammer can say something like on his main account: He bought art from me or he can say i bought his tc. Then the scammer needs proofs no?
