I posted something in jest but then realized it might work. Force new accounts to do the following before they can create an account:

Acknowledge Hong Kong and Taiwan are sovereign nations and that they should not be invaded; Denounce the CCP; Accept that Communism and the CCP is a scourge upon our planet; Make them read up on Tiananmen Square, like one of those corporate training sessions.

Might curb some of them and may also red pill a few. At bare minimum it gives us a chance to say fuck you before they even try.
