I agree with Undeadlink that most networks do not like the traffic source, but on the other hand, if you have found a source of hungry people looking for exactly what the network is advertising, isn't that the point? You harvest emails from CL for people looking for a free IPod, and then send them a offer from a network for a free IPod. You can't get any more laser targetted than that!
My advice is to buy another domain, setup a wordpress blog and sprinkle it liberally with IPod related articles you pull from such places as GoArticles.c0m, etc. Use this site to show your AM where your getting your traffic from, and tell them you use PPC to drive traffic to the site.
When I get asked by my AM to prove my traffic, I always have a site ready to show them, but I act like I am reluctant, and tell them that I have had a previous bad experience with another AM that stole my page layout and designs, and leaked the whole thing to their other affiliates, so I am reluctant to show them. This of course is true, as it did happen to me, but I didnt care because that wasnt REALLY where my traffic was coming from.
Just protect yourself with double meta refreshing of your affiliate url for the offer, and you should be good. You can search the site for how to do double meta refreshing, or if that is too much of a hassle, you can use this service to cloak your affiliate url. Newurl.name can cloak your affiliate url, and the automatically do double meta refreshing as well for it. Its a win-win situation.
