Do You Remove All Evidence That Exists On Social Media After You Split With An Ex? [POLL]

I just happened to look through my friend's Facebook  and she has photos on photos of old ex-boyfriends! This blew my mind.

I understand not wanting to delete good memories, but isn't keeping the evidence like taking a look in the face at your unsuccessful dating history?

Tell me, when it doesn't work out do you delete the evidence? Or do you keep it so you get to take a look back.
