It may seem nice at the beginning, but as you saturate the service with fake clicks, the PPC value will drop to near-zero.

Some keywords are so competitive that they have PPC rates that are close to $100 PER CLICK

For example, anything related to pyramid schemes like Xango, Avon, etc. Keyword space is SUPER competitive for "indenependent distributors" and so their PPC rates are through the roof

MLMs seem like one of the best target for indiscriminate application of AdNauseam, for more than one reason.

Assuming they don't know how to separate fake clicks, which can be done within a reasonable level of accuracy. It ends up being a war between digital ad agencies and the users. I can see who has the most motivation here and therefore higher chances of winning.

Tangential, but makes me think: could all those happy campers who like to DDoS GitHub and Freenode in their spare time target an ad bidding node instead? I'd love to see that happen. Do it for teh good old-school lulz.

Hum... I just thought that we rarely see here a tech showdown from ad companies, or employees (It might be because they'd be bullied to hell), for what we know they could have the most impressive anti-DDoS tech in the world.

Well it would be nice if you could whitelist sites you think are worth the clicks. So, sites you like get a lot more click revenue, because you clicked every add. While the desired effect of diluting PPC would be reduced, you wouldn't be giving revenue to sites that you don't think are worth it.
