All sites that are added to our CyberNOT list mush meet our CyberNOT criteria. I hope this helps. As an artist, I was really concerned when I heard that CyberPatrol was blocking a major art site called Sito.org. This particular site contains fine art from many hundreds of living artists from around the world. Even blocking a subsection of such an art site, to me, seems extreme.
Art is a very subjective thing and each person interprets pieces in their own way.
It's very disconcerting to see a company such as CyberPatrol trying to determing what is or isn't art when your company most likely has little knowledge of the arts. At least this seemed to be the case when CyberPatrol blocked the Sito.org website. I am already concerned about blocking software because it gives alot of power to a few people who determine what should or shouldn't be seen. The ACLU just wrote an excellent white paper on the issues and problems that blocking software and rating systems cause which I encourage you to read.
