Google is cracking down on "super-naughty ads." Its AdWords policies were first posted in March of this year.

Google's message to advertisers reads: "Beginning in the coming weeks, we'll no longer accept ads that promote graphic depictions of sexual acts including, but not limited to, hardcore pornography; graphic sexual acts including sex acts such as masturbation; genital, anal, and oral sexual activity."

"When we make this change, Google will disapprove all ads and sites that are identified as being in violation of our revised policy. Our system identified your account as potentially affected by this policy change. We ask that you make any necessary changes to your ads and sites to comply so that your campaigns can continue to run."

Google's announcement continued: "The AdWords policies on adult sexual services, family status, and underage or non-consensual sex acts will be updated in late June 2014 to reflect a new policy on sexually explicit content. Under this policy, sexually explicit content will be prohibited, and guidelines will be clarified regarding promotion of other adult content."

The national organization Morality in Media praised Google's changes.
