Dear anonymus,
The problem starts when the administrators who are called to
perform those rules are the harrashers themselves and don' t get punished.
A code of conduct should preempt this.
For example [users who can] fly under the rader and be likeable.
[users who] run the annual contests in wikipedia or doing other wikimedia
jobs...
is the code of contact going to apply as well?
Yes. That is the point.
