What if I don't like what my affiliates are doing?

I swear I'm not a control freak...really!

I started out with a private affiliate program (postaffiliatepro) but never did much with it, and it was so encumbering trying to find affiliates and all I really wanted to do is support people after the sale.

So, it was recommended to me that I go digital, (previously my product was a tangible cd and book) and get on Clickbank, which I've known about for years when I attempted to do PPC with other people's products. (It never worked for me)

Here I am live for about two weeks, I got my first affiliate sale (yea!) based on my traffic stats I have about 15 affiliates (yea!) and then I learned that one of them is spamming craigslist with links to my program. (booooo!)

Integrity is a big thing to me...I'm in the work-from-home/flexible job niche, and I have my name and a video on my site because I want people to know that they can trust me. I KNOW that people are thinking that I'm spamming the boards, when really, it's my affiliates.

I can't tell if Clickbank has a way to manually approve affiliates, and frankly, it'd be way too much effort for me to babysit everyone.

Is this just something I have to learn to live with and suck it up? Should I just assume that any exposure is good exposure for subsequent releases of products? Or can I actually set guidelines for my affiliates through clickbank?

Any insight would be really appreciated!
