Since many of the comments on here are somewhat anti-Government, I would say there are a large number of people posting as "AC" in the mistaken belief that it keeps them safe from being tracked down should Big Brother decide that they have been a little too free with their 'speech'.

I have used AC on occasion as it saves hassles at work, from family and friends and means that it ain't so easy for anyone I "offend" to track me down (the Government already knows where I live so I know it's no protection if they decide I'm a threat to Notional Security...).
