Actually I have noticed that one of Nicolas' games gets a few 1 star ratings simply because some of the ads are of a more adult nature. Is there any configuration option in Mobclix that lets you omit such adverts? It seems harsh that the developer gets penalised because of the content of the ads sent to it.

The best ad-network for my experience has been Leadbolt. I have triend admob and Mobclix also. I make about 6 times the money i used to make when i used admob. I use banners, contentlockers and appwall. All are performing really good. Contentlockers give very nice ecpm. When user completes an offer from the contentlocker i give them extra features for the apps. This method is working really well. If you decide to try Leadbolt please use my link
