I forgot to untick Google content network in one Adwords campaign. Kept seeing weird referrers and when I checked I had adwords ads showing up on parked domains

I asked Yahoo and they told me you can only block URLs no option to turn it off completely even though there's Search and Content option, they don't seem to think parked domains fall in the content category

I've no experience on targeting parked domains so it's not working for me at all, just getting clickers that look around and leave
