You could redirect the ad request to a 1x1 pixel transparent .gif file the you dont get the ad and no error message.

And for all those fun spy cam ads that come up in a different page they will get blocked errors. You could ease that by creating a very detailed custom error page. In my situation the level of insanity I would reach after this started isn't worth the effort :) -Shawn
