Flags would be okay but I completely disagree with the stats, stats will be pointless if you're going to hide it, also, impersonating can possibly increase. Because of stats privacy, they just copy outfits and names lol, it happened to me when I was in era, I met too many impersonators of my friend. It can be sometimes annoying that people hide their stats like hell

EDIT:It would be nonsense if youre gonna hide your partner lol unless its a secret
