How does the Stalker Check application work on Facebook?

[Maggie Anne]

Stalker Check, since renamed Fan Check has been deleted.
If it gets re-added, or another like it exists, here are some facts about it:

Yes, there is technology available for free.
There are a few social networking sites out there that let you know what people have visited your profile.
However, facebook is not one of them.

Facebook policy states that no application can exist that counts profile views, or gives you the names of people viewing your page.

In the fine print of the application it explained that it is not actually based on profile views.
It is based on user interaction. Who posts on your wall, likes your status', comments on photos the most.
