I've been blocked twice from using Facebook. The first time was when I tried to register with Oculus to unlock my Oculus Go. I only check Facebook once a week, but still keep in touch with some people, so I went through the process of submitting my ID and phone number and recovered my account. It happened again, because I used a non-standard browser, and this time they can shove it. If they want to keep users they shouldn't block them from using their product. It's abject stupidity.
