Re: Dammed if they do, dammed if they don't.
The term above also implies that they share your traffic with 3rd parties involved in the filtering.
Yes they most likely use someone like Bluecoat that does all the content filtering, and that's exactly what they do. All traffic is directed to them for filtering then passed on, just like most other content filters. Unless you expect some back room bod, to add several thousand sites a week to the list (trust me Squid + Dans Guardian would be no fun to run on a scale that large).
