one of the best scams when i was still a scrub on diablo 2 involved 'hexes', these little charm things that were super valuable and good for trading. you get a different charm that looks identical, and offer the real one to someone for an item you want but is worth way less than the hex. do the trade legit, but have your inventory completely full so the trade doesn't complete. then say, 'ah shit, my inventory is full, let me get rid of some of this junk', then make space, do the trade again but swap the legit hex for the decoy. theyre so eager to rip you off they dont look at its stats and they hit trade super fast. then usually tell you 'HAHA I RIPPED YOU OFF FAGGOT" or something that makes it even more hilarious. i got 'rich' doing that. the best was when i tried to bop a great bow from someone, switched the decoy hex, but they had switched to a decoy bow. lmao. scammers scamming scammers.
you cant do anything close to that in todays games without permanent bans and shit. everything is soft. wheres the anarchy and ruthlessness
