Not when they are a clan leading 6 regions and acting like just one entity.

Well that certainly sounds like you are purposely trying to misinterpret what is being said as it seems rather obvious that he was saying a player's IG family, not OOG family. Banning an entire RL family IG because they are related is certainly not allowed and likely breaks the social contract in more than one way.
