To give an Extropian-list-specific example: determined harassment was why Nick Szabo stopped posting there. The filters didn't help there.
I'm curious: Can you tell me/link me more please?
No; a lot of the materials are now private, I don't think Nick wants to drag old stuff up, and if the harasser was the same Detweiler dude who did some later harassing, he may well have been mentally ill and not really responsible for his actions.
Below is a message I just got from jackk. Some specifics have been redacted 1) so that we can discuss general policy rather than the details of this specific case 2) because presumption of innocence, just in case there happens to be an innocuous explanation to this.
So... thoughts? I have mod powers, but when I was granted them I was basically just told to use them to fight spam; there was never any discussion of any other policy, and I don't feel like I have the authority to decide on the suitable course of action without consulting the rest of the community.
