Usenet was a wild place back in the 90s and early 2000s.
People would get into great discussions, but they’d also fight with each other. And they’d fight a lot.
Flamewars were big arguments between two or (usually) more people. Some people would take things so far as to report people to their ISPs for having arguments on Usenet. It got a bit silly at times.
If you managed to cause enough trouble, you might be labeled a kook. It was a very derogatory label that would follow you around from newsgroup to newsgroup.
