Someone blocking you on Facebook can be identified through several telltale signs:
- You can't find the person in your Friends List or by searching their name on Facebook. If their profile doesn't appear but you know it exists, it may indicate blocking.
- You can't see their posts in your feed or find their profile page, even with a direct URL. Instead, you may receive a message saying the content is unavailable.
- You are unable to send messages to them on Facebook Messenger; attempts to message might result in error messages like "Message Not Sent" or "This person isn't available."
- You can't tag the person in posts or comments, nor can you invite them to groups or events.
- Checking via a mutual friend’s account can confirm if the person is still visible to others, suggesting you have been blocked if you cannot see them.
These methods combined can give a strong indication if someone has blocked you on Facebook, but some signs may also overlap with having been unfriended or the other person deactivating their account, so checking through multiple methods is advisable.
