Problems of flags:
people might not like their country or just the design of their flag.
near country borders they might receive a wrong flag which may let em feel embarrassed.

I experienced much people just not want to be in the same room with me when they noticed my german flag(especially when during a awkward political debate).
German culture nowadays is strange and much europeans have prejudice(which I can understand).

Damn, recently the turkish president had a conflict with a famous german person. When I entered private rooms with a turkish op they were like cyberbullying me(I ain't saying no names or details). And I am not even german!! It was just the flag !!!

Against multiclienting there will still be protection, because the same IP of 2 accounts is marked with a (MC) previous the players name. -We just talk about flag appearance and not the exact location in the database.

All I want is either showing a flag that fits to my real origin, or just disable it.
Not our future but our present is getting globalized, I'm tired of people that judge me because they think I represent germany or whatever.
