I used this program for 6 months and they paid very well. But starting May 2010 they disapproved many (or majority) of their approved publishers, and with no reason. You can visit this Chitika blog post: http://bit.ly/arKRor and learn more what most of their (ex) publishers think about them. If you applied to their program, read this first (taked from their website): So, if you not in this category, don't waste your time, you will not be approved. I personally would not call them as scam, but cheaters.
