Second, you and others involved in this discussion need to stop referring to this software as censoring software. Censorship implies that a work or works have been blocked from the top-down. Since people elect to use this system voluntarily, it's a self-chosen shield, not some government regulation coming down and taping the artists' mouth shut.
Censorship is dangerous to society.
Blocking software is not. Our rights to free speech are IN NO WAY affected by the use of blocking software such as CyberPatrol. You have not been asked by any entitity to stop making drawings of nudes or erotica or whatever. You have not been asked by any entity not to display your work online or in any other media. I think that part is bullshit.
