I agree that the user controlling which were "acceptable" is a good idea, but that's basically whitelisting. My first thought was to have a crowd-sourced list of acceptable ads, but that's pretty easily gamed. Then, it becomes a race between the adblock developer and the people trying to disrupt the system and that's a lot of work just to decide what's acceptable.
With a decent ad blocker or two, the experience is user controlled. No adverts. The fact the people will pay money to block bs and spend time and money to achieve this should provide a clue to advertisers. I go out of my way to avoid products that advertise to me. Hopefully no break though, but as a general rule, if I want a product, I'll seek something out.
