This guy scammed my 2 DotA2 items 1 rare (Bloodstained Britches) 1 mythical (Rotten Stache). The deal was that we agree to get his HOOK for my rotten stache + pudge pants. we made the trade i saw the hook on trade section screen suddently his item (hook) startet to load then he got my rotten stache + pants but i dident get the hook. i dident get a chance to tell him that "can i have my items back ore the hook" but i was blocked and then he keepd changing names, i added nickname on his profile (rotten stache + pants) Hope admins will help me get back my items and ban this Scammer....I couldent get his steam ID cuz he immediatly blocked me and changing names so i couldent get to him. And i dident know about this steamrep untill some days ago. But i have screenshots about his profile side, and inventory how he have my items and next day trading them to something else. . I really hope he get banned and the best for getting my items back =,(

Hoping for the Best...
Thanks
