To clarify, I believe that if you don't think you can adequately moderate your service, then you should absolutely not be running it. If your venders do not think you are doing a good enough job moderating your service, then they should not be forced to do business with you.

All I am trying to say is that it is important to realize that how you moderate your service may very well be judged by your venders and you could have a bad time if they find it lacking....
