I think what's highly likely is that the "hundreds or thousands of Elon's guys" (or 4chan trolls) reported the account/tweet.
Most platforms use some sort of automatic algorithm coupled with an army of people in "third world" countries doing actual first-level reviews and a smaller group people at HQ supervising/monitoring/working on the algorithms.
Well, except...he fired all those people. So now it's probably just "autoban and if there's enough noise, someone comes back and unbans."
When the elon jet reddit user got banned, it was probably the same thing - trolls/bots/muskies mass-reporting after a post hit the front page.
