From the sysadmin PoV it's never "one guy" or even "just two"; what is common, however, is just one or two policemen, one or two soldiers, or one two judges make the news and the limelight of public prosecutions.

It's good to be seen to be tackling this kind of behaviour, rarely ever good (apparently) to fully rip the band aid off and report just how wide spread such behaviour can go.
