We should have a contact list instead of a friend list, because whenever I play, I add someone and after some days I forget why I added them, with contact function, we could Rename our friend, let's say renaming a friend to "Trochus exchanger", but the name was "xxscamzingrobotxx"
And once we rename them, it should be only visible to us, client side and not server side.
But once they're renamed, if we press the profile, the name should return to normal.
It could help a lot of people.
