Facebook is genuinely the most awful app. You get banned and restricted for no reason. Suddenly you just aren't allowed to use any features, but never receive any violations, you're never notified that your account is being restricted, and you are not given a timeline for how long these restrictions last. You go to react, post, or do literally anything and it just says "Your account is restricted". Good luck EVER getting any kind of support whatsoever, because it doesn't exist.
