Something different maybe.

We all need some privacy right? so I have an idea related to privacy. Idea:- A different profile picture for a group of people and different for other group. Lets say you have a profile photo of yours and there's a jerk who always checks your profile picture, so you create a group or tag in your account management, lets call group as *Jerks*, you add the user and set visible profile picture for the group as a flower, the users who are in the group will only see flower as your profile picture and others those who are not will see your original profile picture. Will be happy to see your opinions down below :)
