Is Chitika good?

We were doing well with Google traffic and adsense. We lost ranking first, but adsense was still doing well compared to new (much lower) traffic.
At least it made enough money to cover costs. Then we were eventually banned from adsense with no explanation.
(Official praise and then ban after no change. )
We switched to Chitika. Chitika earns 50 times less than adsense. Maybe because we were approved for silver and not gold.
At silver level we get totally nonsense ads and not related to site topic.
What to do about this? Is there a problem with Chitika or the way we use their service?
Are there good PPC companies besides Google and Chitika.
Good:
-trustable enough, pays well, and regularly.
-doesn’t require phone, address, ssn when applying.
-payment type: paypal, eft (better if not restricted to US only)
