1) If you copyrighted or trademarked them, sure get your attorney on it.
2) If you're on that network and producing better than the thief, talk to your affiliate manager.

- I'm THE superaffiliate in one market and I have an exclusivity contract with my merchant, which keeps the little morons out of my market. Otherwise, it's "death by 1000 cuts". The morons don't stick around, but there's always a new one each month if you don't protect yourself.

PERSEVERANCE is what separates you from the morons.
