That was probably the beginning of the end even if it held on for quite a while after that. (And a lot of other changes were happening at the same time.) Especially outside the alt. hierarchy, which was always more of a free for all, real names usually associated with university, company, or government email addresses and a culture built around a certain exclusivity tended to keep flame wars and and other disruption to a manageable level.

That was the original "Me Too" movement. I remember all those Me Too posts popping up everywhere.

(AOL users were notorious for block quoting long parts of text they agreed with, and reposting with Me Too! above. It's like "This." but less hip, if that's possible.)
