Usenet, MUDs, etc. are interesting as examples which were simultaneously well-known but also strangely ignored as precedents for a lot of the bad behaviour we've seen on a much larger scale.
I think in a way those early examples might have held recognition back because a lot of the most authoritative people had learned “no big deal” back in the era when the Internet wasn't integral to our lives and harassment techniques were far more primitive and less routine (pre-SWATing, revenge porn, social network-driven harassment of people you actually known, etc.), and because so many of the people involved were affluent white men who just didn't tend to attract the kind of persistent hate campaigns which became famous years later. Kathy Sierra should have been a wakeup call but a lot of people shrugged and said “don't feed the trolls” as if that was useful.
