If google moves forward with this we should all start randomly clicking on ads until advertisers start to realize that they're basically throwing their money away on advertising that doesn't work :) Let's hit 'em where it hurts.
Yes, let's beat Google by giving them more money by increasing the overall advertising hit rate in an organic, nearly untraceable fashion. Wait, what was the logic of that again?
There are people who click on random ads professionally, and Google has been fighting them for a long time. Whatever equilibrium has been reached is probably stable. The best thing to do is block ads and to do our best to stay off the grid - the only thing that no statistician can work with is the absence of data.
