Quality Control of 3% volunteers against bullies
Fragment of a discussion from Talk:March 2011 Update
Having seen a fair number of WP:AE threads, I completely disagree with "Even people who are obsessives about some small area can be great contributors and should not be chased away because they espouse one extreme wing of a debate on some point." I takes 6 to 9 months of persistent POV-pushing to topic ban someone for just about the same amount of time if they are civil. (The uncivil ones get indef-blocked sooner). So, someone who is inimical to NPOV but civil transforms a part of the topic area in a zero sum game for 1-1.5 man-years. Food for thought.
