When Facebook decides to shut you out like you're a pesky kid who won't stop asking for dessert. You can't send friend requests or text them anymore. They might have done it because you broke their rules or just felt like it.
My ex F blocked me after I sent 12 friend requests in 5 minutes.
Facebook blocked me for liking 1000 cat videos in one day.
They F blocked me because I used the word 'poop' in my bio.
