I like to keep my ads relevent to my content. I have a niche market, and I expect the ads to be relevent to my market. Google has been doing well on this in the past, however I now have a couple of advertisers who pretend to have relevent content, but they don't, and it is slipping by the google content filter. I guess you would call it adsense spamming.
Anyways let say just for example, my cut was "X" cents per ad from the spammer. If I block that ad, will I be served an ad that brings in only 0.9"X" cents, or are the ads served randomly priced.
