I always been fully legit, no hacked items, but also no dupes, however i do have duped runes now... you just can't get around it anymore.
Anyway i once had a hacked item in my own inventory, someone asked on a other forum if someone could help him mule, so i come in his game, he throws down stuff, and then i see him drop a hex charm, so i pick it up, go to gheed, and sell it while gambling, and then left the game, he was really pissed and complained about it on the forum, so i told him not to transfer hacked items because that forum is based on legit people (common dupes were also banned there) and when he complained more he got himself banned.
Anyway i'm legit, and i did most of my dueling in 76Legit, which is a dueling league for legit people.
