I don't send all my traffic through AdSense, some go to other services, which give me less profits with less rules. I have a CPM around $2. depending on the ads platform. AdSense is definitely the best one for me.
I started with AdSense 3 months ago and I'm still afraid of being banned and lose all my revenue. I don't explicitly violate any terms, but it is not original content and can easily be framed as doorway pages.
