FACEBOOK HELP PLEASE?

Hey everyone
So lately I've noticed all these people trying to create a sneaky more subtle way of sharing their profile picture on fb , what they do is they upload their pic , but then like each night it says they changed their profile pic but it's got like the original date it was uploaded if that makes sense ... It's like they're basically sharing it but instead it says they've changed it but it's the same pic with the same comments and amount of likes etc, I'm just confused how they even do this does anyone know ? Not gonna do it myself just curious. Thanks in advance (:

When you go to you profile pictures and you want to use a picture you have used already it will ask you " if you want to re-use it " or something like that . It only works for me when I do it from my computer bc if I do from my phone it won't have the comments or likes from before
