I see no insult towards you, or anyone else in particular. In fact, to the opposite, others here are saying Usenet died due to lack of content moderation - aka other people enforcing their will on others.
> The problem with post-September usenet was spam.
Now I know you're just guessing. The 'September that never ended' was when AoL peered with internet gateways to bring everyone on the AoL network to the internet, along with knowing little about computers or anything. "Me too" was around then, as a derogatory comment of what an AOLer would say. Even Weird Al in "All about the Pentiums" had a line to put them down like Old Yeller.
Usenet really died in 2007 winter-2008 Spring, when all major ISPs killed their subscriber Usenet servers. They never officially stated why, but grumbles that made it out in the systems engineering folk were that it was alt.binaries were eating up loads of bandwidth, and much of it was 100% piracy.
Spam was a thing, but most of us used good NNCP clients that removed a good 90+% of spam. And having lived through when Usenet was ubiquitous, I fully reject your hypothesis.
And you might want to consider taking conversations here more impersonally. Feeling "insulted" over a comment that was directed to nobody in particular isn't healthy.
