They're also good at vetting buyers. As a merchant, I appreciate the fact that even when the most skeezy-feeling buyers are legitimate. You can get screwed by the customer service requirements, but at least you see fewer customers with fake credit cards and the like. The spam you'd describing is an attempt to get you to rate them. I've sold many things, and the rating rate is less than 10%, so you need to sell a lot to get out of the new vendor ghetto.
