Reporting and blocking
Use the ⋯ menu on someone else's post or comment.
- Report it to the group's admin, with a reason and an optional note. The admin can remove it or keep it up; nobody sees that the report was yours.
- Block its author. Their posts, comments, and reactions are hidden for you (you can still look), and they can't comment on your posts or reply to you. They aren't told, and you both stay in your groups.
Group admins find reports in the group's settings. Unblock people in Settings → Blocked people.
