No. We do not, and cannot, try to regulate what people do outside the game. We are concerned with behavior inside the game, and the treatment and acceptance of all of the players inside the game, regardless of their OOG associations.
If you ask to be a lord in Keplerstan, and the ruler of Keplerstan tells you "No, we only give out lordships to people in our 'l33t g4mezorz' clan", then that is exclusionary, and against the social contract.
That leaves lots of room for people to still exclude players from positions and only give to clan members by making up excuses on why those nobles deserved those positions. I believe OOC clans in any shape or form in unfair play. You have a large group of friends that can coordinate outside of battlemaster and be much more efficient then normal players in the game.
