Not really -usenet of old had stalkers and harassers; that's how the killfile was invented.
That is a very, very good analogy, however.
The internet of old had a wider variety of establishments that you could go to. If you wanted a rough-and-tumble dive bar experience it was there. If you wanted a polished experience it was there too.
The effect facebook and other social media has had on the internet is the same effect that walmart had on small mom and pop stores -you can still find one here and there but no, not really.
Incidentally, for all of the censorship and increased barriers to entry (for creating forums) your drooling meth head still presents a danger in the form of doxxing, inciting riots (Jan 6th, any one?) and harassing people.
