How to block someone on Facebook using a computer or mobile device

• When you block someone on Facebook, you prevent them from messaging you, tagging you, and seeing your posts and profile.
• It isn't easily apparent to the other person that you blocked them.
• You can block someone through the mobile app or Facebook's website.

Given social media's ability to message virtually anyone, there are certain pitfalls with having a profile on Facebook. If you're on the receiving end of some online trolling or harassment, you may want to block someone from messaging you or viewing your Facebook profile. Thankfully, Facebook makes this a fairly straightforward process, and it doesn't alert the other person that you blocked them.

Here's how to block someone on Facebook.

What blocking means on Facebook

When you block someone on Facebook, it prevents that person from interacting with your Facebook profile in a variety of ways. Facebook doesn't tell the person that they are blocked, but there are some ways that they can find out.

Blocks are also specific to each profile you have. This means that if you have multiple Facebook profiles you don't want someone to be able to interact with, you will need to block the person on all of your other profiles.

Quick tip: Blocking someone you are friends with on Facebook will also unfriend them.

People that you have blocked cannot:

• See your posts.
• Invite you to Facebook groups or events.
• Search for you on Facebook.
• Send you private messages.
• Tag you in posts.
• Send you a friend request.
