One can never expect any praise for such steps here on Slashdot. But allow me to put my cents in favor of this ban. First, you could look at Ted Bundy's last interview where he confesses that his career as the America's most dreaded serial killer kicked off due to pornography.
So, I'm to take the learned opinion of a bat-shit crazy serial killer as to what "kicked off" his spree. Yeah, right.
