Easy To Qualify For Ad Networks?

I have been trying to find an advertiser for my website which hosts erotic content (not pornography) and I need an ad network that's easy to qualify for.

I tried using A-Ads but I feel like they are a total scam. Even thought I get thousands of unique impressions per day (90% from the United States) they pay nothing.

Are there any smaller ad networks that are easy to sign up for and get approved?

push notifications system. These guys accept adult & mainstream traffic with instant approve

the erotic content sites is a really big issue as it might lead to get banned from any reason, I will probably select a more stable and honest network.
