Normally, re-directs are not allowed with adCenter.
This is what I got in a reply from the adCenter support when I asked why three of my ads got disapproved. Then it said that affiliates were actually allowed to use redirects, and that the support person would ask their policy team to review and forward results.
This makes total non-sense to me as it is about end destination, not what happens between, unless it's harmful to users.
Or adCenter can't handle it right.
Regardless of affiliates, I know that a huge number of advertisers uses redirects for tracking and other purposes.
Therefore, about that redirects are not allowed - either this support person needs additional training, or adCenter is getting it wrong big time.
Now when they have to excel due to Google smashing bunch of affiliate accounts.
Oh yeah, I do have other redirecting ads running.
