If there's a rule but no way for us to enforce it (via infractions) the rule would be pointless. I think you're wanting everything to be laid out for you word for word regarding infractions. If that's the case, you're right, they don't exist. But my point is that if there's a rule for it (posted in a form of announcements, stickies, notices, TOU, etc), then you better believe there's an infraction paired with it.
