Why'd you leave? I've had accounts banned, and I never stopped advertising on it (just created new accounts). Search still works, content still works. Might not be all of the same offers that you used to get by, but the same kind of thing happened with arbitrage sites and mobile subscription offers before that. I still have campaigns that have been going solid for 3 years, without intervention needed other than an ad copy change once a year. They're not bringing in 6 figures or anything, but it's free money that just keeps flowing no matter the ups or downs of my other campaigns.
Hell, I have 2 rebill campaigns up right now, getting good volume. Compliant offers still can work. Adequate disclosure is not the end of the world.
