Offer me some help!! My site was banned by adsense, adbrite and bidvertiser. :-(

My site was setup six month ago. Now it has about 500 uv / 6000 impressions per day. But the traffic seems not some good. As most visitors are school kids using the same IP address. And also a few persons are using proxy.
I don’t know how to control ads clicks/impressions under this traffic situation.
Do you use scripts to control ads?
Do you deny the IPs which are from proxy？
Do you prevent robots/spiders from crawling you site?
