Have those of you who are still seeing filtered ads on your sites contacted Google Support?
Yes. It was on another similar filter related matter. The resulting response was an email suggesting the problem was from my end.
There's really no point in complaining here if you haven't. It doesn't accomplish anything.
It was this thread that has reassured me that I wasn't going nuts when I previously made my original complaint to Google. Thanks to all those who have contributed to this this thread, I have now been alerted to the fact that the problem is real and still exists.
I would suggest that you rack up a few more posts before you coach other members on what should or should not be posted on a Forum.
