I think that this highlights the fact that the Code Of Conduct doesn't provide enough guidelines about what to do when things go wrong, including determining whether the code of conduct was actually violated.

In this regard, I think it would be helpful to look at creating a WordPress/ WordCamp guide similar to the one that GeekFeminism has, and trying to separate the people involved with the incident from deciding on the consequences of the incident.

These are not easy issues to resolve, but with good faith and transparency, hopefully, the community will be able to learn from this.

Making mistakes does not matter so much as how the mistakes are fixed.
