A site I go to (OzBargain.com.au) allows users to submit affiliate links, but automatically replaces them with it's own affiliate link for readers who aren't logged in, so I assume there's no policy. It seems like a reasonable compromise to me, but that's in the context of a website which is based on sharing discounted products.
