Maybe I'm wrong lacking of the knowledge, but I suppose that the real meaning of the ban is not avoid to show such outfits in the streaming - because for the most they are already not used - rather is to send a message to TK, thing that for obvious reasons can be done from the players but not from Team NINJA.
Sorry if I'm starting from wrong assumptions and I know that the thing concern me just until a certain degree, it's just that I would like to think that it's the right thing to do.
