I don’t know if this line in their policies was recent due to the Stalker Check and Fan Check applications, but Facebook has a line in it’s policies now that would forbid such an application.
Policy: You must not circumvent our intended limitations on core Facebook features. For example:
- You must not notify a user that someone has removed the user as a friend.
- You must not track visits to a user’s profile, or estimate the number of such visits, whether aggregated anonymously or identified individually.
Do you think this is a good thing?
