One of the nice things about the Ubuntu Code of Conduct is that it focuses primarily on the positive. It is long, perhaps overly verbose, but it does focus on what the community wants rather than what the community wants to avoid.
It is easy to say "don't do these things." But it is perhaps better to say "these are the values our community lives by. Please respect them."
+1, except for the overly verbose part.
I probably should have said "overly verbose for our uses here."
I won't second guess a different project with a different scope.
