Apparently my Gallery had NSFW comments..
Google sent me an email the other day telling me that my site had “inappropriate” content:
As stated in our program policies, AdSense publishers are not permitted to place Google ads on pages with adult or mature content.
Adult? Mature? On *my* site? Hmmm, this required some further investigation. It didn’t take long to find the problem- Google even gave me a sample URL. Apparently, sometime in the last few weeks some comment spammer bot found my photo gallery and started spewing link-farm comments in random spots throughout. And of course, the only person who has to do more work in this process is me.
