well, there is a big difference between a democratically elected politician and some random troll.
Could be someone else (who's more "important") didn't like them or just an algorithm problem.
They often have no recourse, and the government tells them "well, it's a private platform, we can't do anything".
There should be a due process (and recourse) at the very least for public figures, and this should not be held privately by corporations but in front of a court.
