Method 1: Tagging on a Facebook Post (Web)

1. Log In to Facebook:
   • Open your web browser and visit the Facebook website (www.facebook.com).
   • Log in to your Facebook account if you’re not already logged in.
2. Create a Post or Edit an Existing Post:
   • On your News Feed or Timeline, click the “Create Post” option, or locate and click on an existing post you want to tag someone in.
3. Type “@” or “With”:
   • In the post text box, type “@” or “With,” followed by the name of the person you want to tag.

Method 2: Tagging on a Facebook Post (Mobile App)

1. Open the Facebook App:
   • Launch the Facebook mobile app on your device.
2. Log In:
   • If you’re not already logged in, log in to your Facebook account.
3. Create a Post or Edit an Existing Post:
   • Tap the “What’s on your mind?” box at the top of your News Feed or Timeline to create a new post. Or, find and tap an existing post you want to tag someone in.
4. Type “@” or “With”:
   • In the post text box, type “@” or “With,” followed by the name of the person you want to tag.
5. Select the Person:
   • As you type the name, Facebook will suggest people from your friends list. Tap the correct person’s name from the suggestions.
6. Finish Your Post:

7. Post Your Update:
   • Tap the “Post” button to share your update with the tagged person.

Once you post the update, the person you’ve tagged will receive a notification, and their name will become a clickable link in the post.

If you want to restrict someone from seeing your Facebook posts, you can use the “Friends Except” feature to exclude specific people from seeing your updates. Here’s how to do it:

On Desktop (Facebook Website):

1. Log In to Facebook:
   • Open your preferred web browser and go to www.facebook.com.
   • Log in to your Facebook account if you’re not already logged in.
2. Create a Friends List (Optional):
   • If you haven’t already, you can create a custom friends list to manage your privacy settings more efficiently. To do this, click on “Friends” in the left-hand menu and then click “Create List.”
3. Make a Post:
   • Begin creating a new post by clicking on the “What’s on your mind?” box at the top of your News Feed.
4. Customize Post Privacy:
   • Below the post box, you’ll see a privacy dropdown (it may say “Public” or “Friends” by default).
   • Click on the dropdown and choose “Friends Except…” or “More Options.”
5. Exclude Specific People:
   • A box will appear where you can enter the names of people you want to exclude from seeing this particular post.
   • Type in the name of the person or persons you want to restrict.
   • Select their names from the suggestions that appear.
6. Finish Your Post:
   • Complete your post as usual, adding text, photos, or whatever content you want to share.
7. Post Your Update:
   • Click the “Post” button to share your update. Only the people you’ve excluded won’t be able to see it.

By following these steps, you can restrict specific individuals from seeing a particular post while allowing your other friends to see it.

Please note that this method must be applied to each post individually. If you want to restrict someone from seeing all your future posts, you can unfollow or unfriend them. Unfollowing means you’re still friends but won’t see their posts, and they won’t see your posts unless they follow you back. Unfriending means you’ll no longer be friends on Facebook.

To unblock someone on Facebook, follow these steps:

On Desktop:

1. Log In to Facebook:
   • Open your preferred web browser and go to www.facebook.com.
   • Log in to your Facebook account if you’re not already logged in.
2. Access Settings:
   • Click on the downward-facing arrow in the top right corner of the Facebook page to open the drop-down menu.
3. Go to Settings & Privacy:
   • In the drop-down menu, click on “Settings & Privacy.”
4. Access Blocking:
   • In the left-hand menu, under the “Privacy” section, click on “Blocking.”
5. Manage Blocking:
   • In the “Block Users” section, you’ll see a list of users you’ve blocked.
6. Find the Person to Unblock:
   • Scroll through the list or use the search bar to find the person you want to unblock.
7. Unblock the Person:
   • Next to the person’s name, you’ll see an “Unblock” button. Click on it.

   • A confirmation dialog will appear. Click “Confirm” to unblock the person.

On Mobile (iOS/Android):

1. Open the Facebook App:
   • Launch the Facebook app on your mobile device.
2. Log In:
   • Log in to your Facebook account if you’re not already logged in.
3. Access Settings & Privacy:
   • Tap the three horizontal lines (the “hamburger” menu) in the bottom-right corner to open the menu.
4. Go to Settings & Privacy:
   • Under the “Settings & Privacy” section, tap on “Settings.”
5. Access Blocking:
   • Scroll down to the “Privacy” section and tap on “Blocking.”
6. Find the Person to Unblock:

8. Unblock:

After you’ve unblocked someone, you’ll be able to see their posts, send them friend requests, and interact with them on Facebook as you normally would. Keep in mind that if you unblock someone, they won’t automatically become your friend again; you’ll need to send them a friend request if you want to reconnect.
