DIABLO 2 WALLHACK

Last evening i wanted to trade a unique charm called "hellfire torch". usually u trade such items in act 1 near akara. each person throws item on ground an then u say "go" and u take the other item.
but now a guy (account *janis-fallen1) used some kind of wallhack.. he teleported right to my side and picked up my charm. :( the charm was worth a PUL, maybe even an UM rune... :(
im so unlucky....

orly? yarly. blablarly
