Did Yahoo/Bing Ban adult ads?
 

There are no adult ads for any adult search term today on Yahoo or Bing. Does anyone know anything about this?

I believe this went down in late 2012. I think I read (but can't find the article) that it was a policy change the new Yahoo CEO out in place.

Websites Should not contain Adult, Pornographic or any illegal content

You can still run adult ads, but you have to contact Bing directly to set up an adult account. You can only run a list of keywords they approve and supply to you and they have to be exact match only. I found the volume to be an issue due to this.

The reason is it's a pain in the arse to do. You can run adult ads but they need to follow a strict set of keywords and your site cannot contain any offensive content.
