Here is my initial gleaning of the situation.
Some bad decisions were made. We need to have more clear policies on banning and involve the site in complicated banning. We are not a hierarchy. This is everyone's site.
We need to stress more reading of stickies. It took me a long time to find the anon mama sticky, so we should work on visibility.
It is so easy to get confused and mixed messages over the internet. Life doesn't happen in real time. Someone offline for a day could have missed this entire situation, but it will take much longer than that to rebuild the integrity of the safe space
