If a restriction has been imposed on an individual app, as a rule, you first need to fix the app itself in the marketplace, after checking it and publishing an update, send it to admoba for checking. Admob usually checks in a few hours and starts showing ads pretty quickly (it seemed to me that immediately; at most, on the same day).
If ads are restricted to the whole admob account because of suspicious traffic, then it's 1-4 weeks, and sometimes more. The reasons are not clear. But if anyone has a clue, please write me a PM and we'll discuss them, because I'm struggling with these restrictions since last summer.
