If the script is php based you could place the adsense code on its own php page and include some geo-location and ip filtering to the file before it is included. This may slow down adsense load time but will allow you to block the loading of adsense by those you filter... such as anyone loading more than x pages in y amount of time.
Then, in adsense, approve only your domains and sleep peacefully.
side effect: you'll compile a nice list of nasty IP addresses in the process.
