It always irks me when i see something like a school domain or a cancer research domain that goes expired and ends up being filled with porn.. this would be fairly easy to spot/catch but they dont, because the more irrelevent the results , the more relevent the ads seem..

Guess why google has never tried this approach very well ... because if you found relevent results you wouldnt use adwords/adsense and they wouldnt make $$$
