If someone is on my list (the person I was thinking about writing this to, a few minutes ago, isn't, but it reminded me), if they're not in my family or family material, participating in such boneheaded things as (but not limited to...) anti-downrater rampages; bulletins or blogs targeting people for things that aren't violations of the law or of the Terms of Service and essentially inviting others to harrass the people linked to; -- at my discretion of course, always at my discretion, I will often just ignore this it's true- but I will delete and perhaps block not the person in the bulletin, but the person posting it, or the person on my list following the link. (Or both, if I need to.) (If it really is a ToS violation, though, a bulletin is generally not the thing to do- write a bouncer. They won't and shouldn't answer other interpersonal spats but Terms of Service violations - like hate speech incitement - _are_ up their alley. Provide evidence- of course.) (If it's interpersonal but not a spat the police are probably the people to call, I suspect, not the site admins...)
