Make Glype Proxy Harder to Block By Filter Companies

My Glype sites (e.g. [login to view URL]) are very quickly blocked by the likes of WebSense, SmartFilter, M86 etc. Looking for a way or ways to stop them being so easily picked up and blocked. I have tried SSL, blocking their IPs, changing my ips - need some new ideas. Cant break Adsense TOS nor stop Facebook/Youtube working) May well pick more than one bidder. Please briefly describe your idea.
