Its annoying to me as it's not supposed to be doing that. And unfortunately there is no way to tests the ads but on the live board. If I try doing any of this on a private test site none of the ads display.
As you can tell I have been screwing with the ads for the past week now, trying to figure out the magic combination to increase earnings for the site as we have a $6,300 bill due next month for bandwidth.
The ads were doing good then just stopped working for things that we were earning $1 on we are now earning 30 cents. I was told to move the ads around in order to find the "hotspots" which would help out and bring the earnings up again. So every few days I put some ads up and see how they work. If they dont work then I move them somewhere else trying to find the magic slot.
If I had a choice (or if I won the lottery) there would not be any of the syndicated ads.
