During lockdown, my son's school delivered lots of material through Facebook. Despite quitting 8 years ago, I signed up again. I didn't add any friends or make any posts, though, and within days the account was blocked. When I tried to sign up again, it said my phone number was blocked. I contacted the "you've blocked my account in error" service twice, submitted documents - didn't hear anything back.
