I worked on this before. You can solve the privacy issue using "statistical payments", by lack of a better word.
You visit website A,A,A,B,C,D,A,A
At the end of the month, you send your entire 20$ randomly to one of the websites you visited.
This will level out everyone's contribution and reward websites with lots of traffic. It eliminates the need for micropayments.
So I set up my own website and put a book on the F5 key to nearly guarantee I get my own $20 back. I also hotlink images from it to Reddit.
You can look into international call termination fee fraud in the public telephone network, for more on this.
