How to stalk someone's instargram's followers

[DevinciDemon]

well basically someone I know has X amount of followers which I believe he has bought most of them but in order to find it out I guess I need some way to check how many followers he's been getting daily data for the past month - 2 weeks or whatever..
Is there any website that can provide that ?
