What do you mean by rejected? Did they supsend your account or just take away the sales from you? Did you violate some policy or were you clicking your own links?

IMHO Youtube is the best traffic driver and click driver in terms of Amazon Affiliate stuff. Doing product reviews. Somethign you may want to consider is start getting free products from Amazon through review sites like Jumpsend, AMZReviewTrader and Snagshout and then review those products on Amazon and drop a link.

If you're not familiar with the concept of review giveaways and stuff her'es a really old video I made kind of explaining how the process works.
