Sometimes having an account in a social networking website like Facebook can dampen your mood. This happens when you come across people who pester and harass you or you feel the need to avoid being searched by some people. Whatever your reasons are, there is a fast and easy way to block a person on Facebook!
1) Click on the settings link situated at the top right corner of your profile page.
2) Click on the manage link next to the privacy header.
3) Key in the name of the person you would want to block in the block list search box. Select the relevant profile from the search list and click on “Block person” link next to his profile. You would no longer turn up in the person’s search results he/she would not be able to visit your profile anymore.
