"People You May Know" is a Facebook modification to add more friends in your friend list.These peoples might be a friends of your friends or they also studied or has been studying in your college.But most of the Facebook users said that we didn't like this ,if we want friends we would add them.
I hate this features because most of peoples are unfamiliar to me,may be there are my friends friends ,that not a reason to add them in my friend list.There are many methods available to block or remove People you may know from Facebook.But i found this method as a usable one.This method can be applied to both Mozilla Firefox and Google chrome, but for Opera and Internet Explorer this method won't work.This extension/addon not worked with Internet Explorer and Opera.
