(More cynically, I suspect the real difference was that blocking on Usenet was less effective and easier to circumvent so no one felt the need to use social engineering against it.)
@ghost_bird I think it is the fact that on Usenet you didn't know if someone had blocked you.
@Canageek Good point - I don't see people making the same fuss about muting or shadowbans. (You could *plonk* someone on Usenet, of course, but that was an optional performance.)
Anyway. PSA: block early, block often, block preemptively, block with regexps, block on a whim, block individually, block by association, block because you don't like their profile pic. You're setting boundaries, and setting boundaries is care.
