> At which point in history could any person blurt out a brainfart and have thousands of people around the globe hear it and react instantly again?

Usenet, for several decades already. Good NNTP servers had nearly perfect spam filtering and the trolls were handled individually by each user in killfiles.

If Google had kept the simple original web interface from around 2004 we might not have had all these issues. GPT-3 spam is hard to detect, but can be handled by killfiles.

Of course the real goal of Twitter is to do user profiles and possibly log private messages, for which Usenet isn't suitable. I wonder who on earth would send a sensitive "private" message on Twitter.
