Yes, some advertisers accept incentive traffic. Make sure you fill out the "Special/Incentive" description, or else you'll get kicked out of CJ.
no, you wont get kicked out, they will send you a warning to mark ur account as incentive or special traffic. You can open another CJ account exclusively for incentive traffic and u shd apply for advertisers in that. Dont mark it in ur current CJ account, all the approvals will go to pending again!
It's happened before, and it'll happen again. CJ has & will kick out publishers (and reverse commissions) for incentive sites when they mess with the big advertisers - especially when they do that with free lead programs.
