Well, it's certainly of paramount importance to protect all WMF sites from hosting educational content on such verboten topics as Managerial Ethics, Due Process, Human and Civil Rights, Scientific Hypothesis Testing, Evidence-Based Reasoning, and NewYorkBrad's Guiding Principles for Wikimedia Functionaries.
Range blocks should be reviewed much more actively. Better tools may help here. But Moulton, despite your good intentions, please understand that you are one of the editors who drives others away.
I am attempting to drive away the toxic Cluster B Control Phreaks who have transformed an educational enterprise into a lame clone of Zynga's Mafia Wars in which good faith editors are routinely kiboshed by an adolescent cadre of Keystone Kops with tin badges and toy banhammers.
Let them go play World of Warcraft or Rift or one of the free Zynga games on Facebook.
