How trade without traces ?

Hi guys,
I've just hack a player, steal all his stuff, send to me by letter. After that I trade the stuff to another account and a second computer, using right click "negociate", I do this with a 3rd account and delete the second account but 24h after I was ban...
(I change my IP adresse between each operation)
Do you know any solution to not be ban ? What GM's can see ? Chat,letters,trading and auctioneer ?

up :(

Ehm... They can see it all.
The database contains a complete log of everything.
And anyways, you know these guys have spent over $200 to get these.
Don't steal them!

If you don't hack, you don't have problem.
