Yes its around 60% search engine. Every once in a while a school still finds it. I assume the schools that do are low budget schools that cant afford the fees of the filtering services. Not sure though. Last school I can recall was Wilson in SoCal as they loved the chat room. Adsense off it covers my server bills and my Cox cable bill. The income from the other ad networks on the proxified page are what I use to fund my other projects.
