Anyone who's used Usenet will be aware of Mike Corley - the MI5 guy. He has been banned from most UK ISPs for breaching their TOS - his rate of posting to Usenet was prolific.
Responses to him ranged from people interested in him as a person, and in his treatment (or lack of); through to hostility at his very many posts and his attempts to evade filters; to really unpleasant baiting of a person with a mental illness or nasty mocking.
Would love him to read a (short) autobiography some day, he does seem incredibly interesting, smart, intense and of course somewhat unstable.
For anyone interested, here's a video in which he introduces his OS: https://www.youtube.com/watch?v=WAr-xYtBFbY
