And having a code of conduct is a sign that this place is so terrible so regularly that it needs a code of conduct to get people to be civil to each other.

OR, everyone in power is a satirical HOA tyrant type character whose primary hobby is rule-making.

Either way, code of conduct is also generally code for grumpy and to be avoided, lest your time there be spent in moral lectures and petty arguments instead of on whatever the ostensible topic is.

I try to go places where people get along without a codified list of civil behaviors, because then I know I'm in the company of adults.
