== How many defamatory edits before an established editor is blocked? == 

 *Barbara Osgood "Philip Milton Roth (born March 19, 1933[1]) is a well-known arsehole and novelist."  Earned the editor (well-established since 2006) a mild rebuke .  Then someone else spotted this contribution on 22:11, 7 May 2010 "David William Donald Cameron (born 9 October 1966) is a cunt".  Editor now blocked.  So the rule is that calling a world-established author "an arsehole" gets a telling-off. Calling the Prime Minister a 'cunt' gets an indef block.  Actually I see that if the editor says it won't happen again, they will be let off. Fair does.
