can't block someone on facebook and I never blocked that person before?

[William]

I can't block anyone anymore just says like error we're trying to fix the problem.

Is anyone else experiencing this?

[Athul AS]

Is that mark zuckerberg you are trying to block?

[Robin]

You can block someone to unfriend them and prevent them from starting conversations with you or seeing things you post on your Timeline.

Blocked can also mean that Facebook has temporarily restricted you from using a specific feature or multiple features, but you can still access your account.
