The anti-scam site I was referencing specifically dug into (by name) certain so called "high yield investment programs" that are heavily promoted on the web through multi-level marketing deals. The price per keyword can be quite high. No one of reasonable intelligence attracted to the particular anti-scam site would buy from these advertisers, but they may well know that clicking a lot on the ads will increase the advertisers' costs. So, from the advertisers' perspective, this is the last site they would want to be on -- especially since invalid or 'fraudulent click' complaints would likely be high.
The point here is that if one's site goes against the flow of the advertisers -- it is not simply a review point -- bad things can happen to the Adsense account.
There are risks worth taking, and others, not. If the site owner's intent is to act against the interests of its advertisers, the final battle could well be won by the advertisers who, upon complaining to Google, succeed in having the Adsense account yanked.
