I want to block these people from seeing my profile picture on facebook like all of them, I've blocekd them from my pictures but I can't seem to block them from my profile picture. I don't want to delete them as a friend.
So, how do you block people from seeing you profile pictures?

Go to where it says settings then click on privacy settings. Click where it says profile then you can change you can picture settings. Then make sure you save it.

Just go to privacy settings and then go to profile and set profile pictures to private.
