I scammed people on Diablo II waaaay back when I was 14 years old.
I'm not sure if it still works today after all those patches but back then there was a neat little trick you could do to scam people's items off them.
I always went into diablo run servers, waited until one of the players there died, then spread a huge bunch of cheapass items around their corpse. Once they came back, they usually clicked really fast on their corpses, to be able to get back into the fight. Most of them clicked on the cheapass items I put there 2 or 3 times before actually clicking their corpse. Which means, they picked up 2 or 3 crappy items, then once they clicked their corpse, they would auto drop most of their corpse inventory items because their real inventory was already full with my crap items xD
All I had to do was stand next to them and quickly pick up their good stuff ^^
I collected some pretty damn neat gear like that.
But yea I feel kinda sorry for it today, I think I made many players quit because of that =/
