You are not eligible of viewing others private facebook profile.
Because they have restricted you for viewing you their facebook profile.
Facebook gives such a vast privacy setting that any other web sites offers.
For having a view in facebook just go log on to the facebook account
Then go to the account option which is at the top of the
right side of the facebook account click on it.
Then a drop down menu will open and then you will have to select a privacy
setting and there you can select your own setting you want to privacy.
I hope so that this helps you a lot.
