Leftists only got banned from twitter when their calls for violence and destruction became too blatant and noticeable to let slide, and thus had to get scrubbed. Conveniently. One exception to this rule was the psycho commie squirrel that supposedly got banned due to a report flood by nationalist indians, and glenn greenwald intervened and had the squirrel revived.
The reason why there was a mass influx of conservatives, gender critical feminists and a mix of heterodox bloggers, minor columnists, and of course the closeted nazis to twitter after musk took over was obviously that they were the ones that constantly got gass... sorry banned by the twitter jannies, a perpetual process of elimiation that didnt stop until the progressive cat ladies with moderator powers at the twitter offices had all left the company because their only job qualifications were to kill peoples accounts and post the standard leftist vomit on their sockpuppet accounts.
