It's all fun and laughs until something goes sour. You just haven't reached the point where conflict may arise.
If someone in your faction slacks off, would you not strive to replace him/her? If that person is a supposed "friend" and you, as the leader, elects to retain that member, how would the rest of the faction feel? You can't appease everyone. That's how conflict can arise and sunder your online "social" relationships.
