I think it’s the demographic that has changed most markedly but even then discourse still rhymed with today’s dumpster fire. Sure, that monoculture of geeks had a veneer of community but that’s all it was.

Spam and bots showed up early enough I remember having to deal with garbage in email and Usenet. Even if it started with harmless crap like sending Marty Shergold style email forwards and whatnot. It was no paradise although admittedly it seemed to degrade fast from the early nineties.
