Ad Networks that are easy to get accepted into?

Does anyone know any ad networks that are easy to get accepted into?
I was wondering because I have a small site which I want to diversify its income which is hard because alot of ad networks do not accept it because it has a low amount of traffic.
I tried
Adsense (just need any site that doesnt run porn/viruses)
Adbrite (literally any site)
Claxon Media (you probably dont even need a site to get accepted)
So please reply if you have any suggestions?
