Well, let's say that a scammer (of art) made an alt for scamming. He stole HQ art, and then sell it on this alt. Then he send all the TC to his main account.

My question is, if this happen, a market squad will ban this alt or his main account? I mean a anybody can look to his old trades no?

No no no, i mean, he stole art (doesn't mean on what account) and sell it on this alt. Then all the tc he made will be send to his main. What account will be ban?

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?

Oh now it is clear for me. thx.

This account isn't mine xD, that name of my main account is from a friend steam account and i used it. And my friend used the same name for his account. And now he didn't played toribash for a while and he gave me his account, and i rarely use it.

What do you mean with account sharing??

Oh, i understand now.
