This has been my approach for the last 10 years: I live to make adversisers pay out the nose for my attention, then I don't buy products. I'll fill out surveys, invent names as long as the terms are vague enough to allow it, and do anything in my power to give large data-miners as much information to choke on as possible.

I personally think the best way to fix online advertising is to make it so expensive that door-to-door salesman suddenly make financial sense.
