You've got to be kidding!

The fact that Usenet was a protocol, with no favored UI (not even a web UI) meant that you could implement "only ignore them" in a totally reliable way. Indeed, this feature was so commonplace that it even had a name: a "killfile".

Killfiles were local to each user which is good since each person could control what they saw. It was bad because new users who didn't know about killfiles would see the bad actors. It also meant that could have disjoint conversation so it felt like each thread was its own thing. You would have to keep telling people to not respond to the trolls.

The ideal is to have a global filter by moderators for the bad actors, and user killfile to tune that.

Usenet killfiles are not "totally reliable". Nym shifting has always been a thing, even before Google Groups-based commercial mass spamming using constantly changing From: lines industrialized the problem. Killfiles also do nothing for people quoting the person you are trying to ignore, unless you use a thread-based killfile, which of course means you won't see a lot of non-killfiled people's comments.

At the end of the day, there is no satisfactory solution to the problem of warped and damaged online personalities other than actually preventing them from being online, which of course has its own difficulties and consequences.
