To see if someone has blocked you on Facebook, you can check several signs since Facebook does not notify you directly when you are blocked:

• Check your Friends List: Search for the person in your Friends List. If they don’t appear there but you were previously friends, they may have blocked you or unfriended you

• Try to find them via Facebook Search: Enter their name in the Facebook search bar. If their profile does not appear and you know their account is active, they likely blocked you

• Attempt to view their profile directly: If you have a direct URL to their profile and it shows “Content not available” or a similar message, it is a strong indicator they blocked you

• Try to tag them in a post or invite them to events/groups: If you cannot tag or invite them, it suggests they blocked or unfriended you

• Check your Messenger: If you cannot send them messages or get an error like “This person is unavailable on Messenger,” you may be blocked

• Look for their posts in your feed: If you suddenly stop seeing their posts and you know they are active on Facebook, they might have blocked you or changed privacy settings

• Use mutual friends: Check if mutual friends can see or tag the person. If they can but you cannot, this is another sign of being blocked

No single method is foolproof since they might have unfriended you, deactivated their account, or changed privacy settings. Combining these checks will give you a clearer idea if you have been blocked

. In summary, the main steps to see who blocked you on Facebook are:

1. Search for them in your Friends List and Facebook search.
2. Try to visit their profile directly.
3. Attempt to tag or invite them.
4. Check messaging ability.
5. Use mutual friends to verify.

If all these fail, it is very likely you have been blocked by that person on Facebook
