The truth. That I was a very long-time member, very regular participant, and I had done nothing that would be considered fraudulent or a violation of the rules. I was polite, expressed my appreciation for the program, as well as any help they could give me in reinstating my account. E-rewards did, Opinion miles did not. Of the two programs, losing e-rewards would have been a much greater loss.

Here's my caveat: This is going back several years, so no telling if either program is currently receptive to a request for review. I do recall that at least one of the incidents seemed to be the result of a technical problem on their end, but they never explained what happened, just that I was reinstated.

EDITED TO ADD: I'm a pretty fast reader, and it's my understanding that some of these survey programs will ding you if they think you're blowing through the survey without giving much consideration to your answers, so that might have tripped me up, not sure. I have since made an effort to slow things down a bit when I answer surveys, just to be safe.
