Then we thought about what might happen when we have a violation (endless discussions about whether that was actually a real violation and whether our response was justified, maybe even within the team).

So, we sat down and wrote a slightly longer version, which tries to spell out some unwanted behaviour and some guidlines for conference stuff ( http://socrates-conference.at/code-of-conduct/ ).

We also wanted to explain why we have the CoC in the first place and how we'd like people to behave. It surely is not perfect (probably too long and too short at the same time).

But if you think "don't be a dick to other people" would suffice as a CoC, imagine you are the organizer of an event, and then try to list all the things that might go wrong. Be creative - I'm sure you can imagine situations where it does not suffice.
