Hard to say.

I say that we dont' accept sales from "Unwanted mailing" or any other illegal or misleading means. I think that spelling out every single shady way of sending traffic is going to eventually have someone come up with some new shady way of sending traffic and it won't be in your terms of service.

Spammers and scammers have always been two pages ahead of us so I'm going to say "Vauger is Better."
