I don't like this idea. Yes, you got the additional option which is to be anonymous. Just saw someone in-game earlier been talking bad about countries or being a racist. How about the players who doesn't even know where to change the settings and doesn't care about the scores/flags/etc, and just play the game for their past time? It'll be harmful and can cause cyber bullying. If a player wants to have friends, then just be friendly towards players.
