I’m not entirely sure, because I’ve never gotten the hang of Twitter. But reading between the lines, I think this is the sequence of events:
Libertarian twit tweets a death threat against Harris.
Libertarian twit is reminded of the rules (and common decency) and removes the offending tweet.
Libertarian twit passive aggressively tweets about having removed the tweet they twote, invoking the promises of free speech to imply that Leon was censoring their tweets and trampling on their freedoms.
Leon responds to the complaint with the tweet the twit twote, simultaneously demonstrating that the twit is a twat and amplifying the message.
I feel like this has been done. There was an AI generated “debate” between Biden and Trump that was mostly swear words. But it was trained on their speeches and was mostly gibberish and insults.
Edit: It was on Twitch, and users could add inputs and questions.
