Wytze nailed it...
No more adult ads... in the diagnostics tool... it says:
"Ad not shown | Reason: Your ad is awaiting approval to appear on Google for this search term."
They are fucking the adult industry. There have been people around here, like me, going through a series of adwords issues lately centering around the "Teen Porn Concepts" issue that arose earlier last week.
I will guarantee this is the root of the entire adult system being placed on hold. I bet they are trying to figure out exactly how to proceed.
Fucking ridiculous... hey, let's implement a new rule while not having the rule truly defined.
AdWords!
