Maybe about a browser extension that loads every ad, but there are no clicks. Preferably the browser makes the ad un-clickable (if it's visible at all).
Now you've got advertisers spending money on creatives, building campaigns, bandwidth, monitoring/management, etc. but there's an almost zero chance of generating revenue. Would that be more effective?
This is preventing the ad campaigns from building a database about your personal preferences, building a profile on you. Also this way the advertisers are spending even more money, by paying for those clicks. If the goal is to make advertisement cost more or provide some sort of political statement, then this is surely more effective. (Regardless of whether the goal is really that great.)
Edit: But are the advertisers really paying for those clicks? Reading through the thread, it seems like these get flagged as fraud pretty easily. So while there's still a cost to create/serve the ads, to the point of my question, it would seem they don't pay the websites for the clicks.
