Bidding on brand names prohibited

I'm working with a lot of campaigns that don't allow brand name bidding, yet I am still doing it on some.
Is there anyway they can track me down and find out?
I don't want them to cut off the commission after a whole month of getting them leads.
Thanks

I don't use adwords (to much trouble)
I am simply promoting cpa offers with other search engines.
What do you mean by cloaking?
