<human>:  How do I block someone on Facebook?
<bot>: To block someone on Facebook, go to the person's profile page and click the “…” button in the lower-right corner of their cover photo. Select "Block" from the dropdown menu and click “Confirm.” Once blocked, they'll no longer be able to see things you post on your timeline, tag you, invite you to events or groups, start conversations with you, or add you as a friend.
