Kida is right. Its our fault if we trust some assmonkey who is trading some super powerful sword and we get scammed. I've been scammed plenty of times on Diablo 2 and games like so, and I bet many others have obviously. Its best not to bitch because you won't get anywhere, and face it, can one person really fight a company making money of peoples unspent hours? Thats like a sheep versus a wolf in Mortal Combat.
