Admob alternatives?

What are the other alternative ad networks do you use beside admob for CPC/PPC banner and interstitials ads?
I’m thinking about switching from admob because there has been complaints that AdMob banned people and took their earning without any reason and accusing them for ads fraud.
I’ve tried inmobi but the ecpm and fill rates are not as good as admob.
Any suggestions?


For interstitial ads I’d give mobileCore a try.
As of late I am seeing better rates than every with them on several of my apps. They pay weekly for revenues of $200 or more too, which is great.
If you sign up through my signature you can earn a bonus of $100 once you’ve reached 100k impressions.
