Google Ad Status:

If you do not understand something or are frustrated with something in particular
feel free to voice you opinion online or see if it can be resolved through talking to
your ad representative. Google AdWords has a blog (which does not want direct
AdWords feedback), an online support center, and you can contact Google
advertising via phone at 1 (866) 2 Google.

Due to trademark issues some ad copy will be rejected by the automated review.
When that happens you can request an exception and the ad will get a human
review.

Google usually runs most ads before they have an editorial review, but they review
them before placing them on partner sites. I have seen long review times in excess
of a few days for Google site targeted AdSense ads.

Ads on Google.com have two states: active or inactive. If an ad is inactive you can
make it active by bidding higher.
