Is it really possible to know "Who Viewed Your Facebook Profile?"

• Are you eager to know what sorts of people visit your Facebook profile?

This is quite natural. People who use social networking site like LinkedIn, Orkut and MySpacecan get to know this by tracking the visitors and can view the profile of the visitor. This feature is missing in Facebook. However, there are few applications that let you know who visited your profile. But, speaking truly these applications cannot be trusted in terms of efficiency and security. Below are the oft spoken apps that claim to track profile visitors.

DoorBell:

This app has more than 30,000 visitors currently. This is not very accurate as the user has to click the doorbell to get the stats recorded. This apps lets you put a doorbell, so that you get to know who visits your profile in Facebook.

Unfaced.com:

John Arrow, who developed the Unfaced.com apps, has been banned from Facebook. This apps is the only one that really works on Facebook. However it is against the rules and regulations of this social networking site. In fact Facebook tried to get into terms with John Arrow and suggested deleting the site, so that his Facebook account can be reinstated.
There are criticisms that Unfaced.com is a scam and cannot be relied completely. You cannot use this tracker site on your profile, because it is a violation of Facebook terms and your account will be terminated.

What is the reality?

Anybody using any form of tools or applications to track the people who visit his or her profile is against the terms and conditions of Facebook. When such applications are used Facebook may delete your account without warning as a breach of terms. The applications that claim to track the visitors’ profile are not owned or authorized by Facebook.

Fake Applications:

Most of the applications for tracking profiles are fake and fraudulent applications. They may be owned by hackers. They may also contain virus. In such cases, your Facebook account may be exploited by them for their own benefit. It is better to extremely cautious as these activities may turn you in bad light, for no fault of yours. Again virus tools may also lead to malfunctioning of your system. Few applications are well designed to get information about your email id. These will not only lead to unwanted marketing emails being received, but also, all your personal information can be tracked. Imagine what if your bank transactions are followed by your mail id? That is the worst that can happen.

• It is never possible in Facebook for applications to see who has viewed your profile. Even the News feeds and other community feed applications, cannot track this piece of information but only see who keeps replying to the news feeds and people who are engaged to a specific sort of posts in a wall.
