Someone already "hipped" me to that ad. (thanks)
The ads are automatically fed by google based on the words that are on the thread therefore questionable ads are likely in certain threads.
I can block the ad (which I did with that one) and within a few hours the ad will not longer show in the rotation.
If anyone ever sees a ad that is inappropriate please email or PM me the URL of the ad (not the title of the ad but the web address) and I can add it to the "blocked" list.
Oh, cool. Thanks.
