1. Does YPN pays to publishers more than AdSense ? 2. Is the "click-fraud" thing takes place in YPN too ? 3. Does YPN handles click-fraud like AdSense - like inumerable AdSense accounts got banned ? Thanks.
1. In general, Yes. 2. Yes, of course. Where there is money, there is someone trying to cheat. 3. Yes, banishment is just as easy with YPN. The fact that there are infinitely more Adsense publishers than Yahoo publishers just makes "problems" associated with Adsense more pronounce.
You could be forgiven for thinking its only Google that bans accounts because it seems only people getting banned from Google complain here. However, it happens with YPN as well, but you must remember there is only a fraction of the people that use adsense use YPN.
My best guess is YPN and Adsense are using a similar strategy. Because they're in a same business area. For YPN to gain market cap, they need to pay higher than G, thus, their margin is smaller than G (still my guess).
