I can see blocking being useful for schools, but not colleges. When I went to a state University, as long as the content was legal, I could view it. This included adult content on lab computers. The lab assistants would kindly ask you to move to another computer if your offensive content was easily viewable by others. Labs were also open to the public for local residents. Students doing homework always got priority.
