Blocking is a useful feature that helps users keep unwanted contacts away from their Facebook profile. It can be used to block personal accounts, business pages, and other user groups. Users can also block specific URLs that they don’t want to see ads for on the Facebook Audience Network.

Facebook block list accounts will not be able to see your public posts, comments, likes, or tags on other people’s content. However, they will be able to view your own private posts and will be able to see your name in public groups. Blocked accounts will not be able to follow or add you as a friend, nor will they be able to attend your events.
