I have been thinking of implementing this feature to my website (not a dating website), but I did some research why Facebook does not use this function and I am very surprised.
It seems like a lot of people would like to see who visited their profiles.
So why is Facebook so afraid of this function and is it actually a good feature to enable users to somehow unlock this functionality (by unlock I meant for example if the user is registered 5 months you get this privilege or something like that).
Would it be harmful for the functionality of entire website to have this feature if people only would be able to see who has visited their profile without sharing this information?
Any cons and pros why it would be good or bad to have this feature?
