that depends on what u mean with hack items! :eek:
if u mean with hack items, items which u had get from a hacked acc, yes gms are able to find them because of the reason that every item has an own id! that means, u have two aoa, one of them has an id and the other has a different id!
BUT: on a private servers the gms are too lazy to check the idīs of items! on official servers its another thing! there the gmīs using special programs which helps them to find the hacked items!
hope that helps!
