Isn't that what the nofollow attribute is for?
What gets me about 'the paid link question' is there are sites I would happily pay for a link on - they are on-topic and their traffic is perfectly matched to what I can convert. But I can't help them out that way, by Google rules. I can only beg them to link to me in a 'but think of the children!' way. I don't like it - don't they deserve my buck?
