Facebook block account or facebook jail
Facebook jail is when Facebook throws you in a virtual prison for breaking their rules. You can't do anything on your account until you get released.
My friend got Facebook jail for sending 50 friend requests to his crush. He couldn't log in for a day.
I got Facebook jail after I posted a video of my dog wearing my dad's hat. I had to wait a week to get out.
My cousin got Facebook jail because he posted a rant about his teacher and got blocked for a whole day.
