Did you ever think to change the type of ads you are showing on your site? I'm saying this under the assumption that you are using an ad platform where you plug their code into your site and then they show your user's ads.

Have you thought about handling the advertising yourself and hand picking products and services that are directly applicable to your users and displaying them in an unobtrusive manner?

And as a side note: I consider ads from any ad network to be a security risk and while I respect sites for "politely" asking me to whitelist them I feel it's a misguided approach.
