> Are the users just blindly approving trades worth thousands without even verifying?

People do. Many years ago I started playing an MMOG and the old timers were all discussing some incredibly rare new item. So I said I had one, and someone said he'd give me 100 million credits for it. For comparison, I'd just spent several hours grinding out about 10 credits. So I sent him a formal offer - some random piece of junk for 100 million credits - and he was so excited he clicked OK without reading what he was getting. He was so angry! He spent weeks spewing venom on the forums.

Of course, this wasn't real money, but in terms of time spent earning it he suffered a significant loss.
