I wouldn't mind seeing some more detail, Sarah. Holding folks accountable for their judgment is something we can do without the Foundation's input. I think its clear to everyone that part of the problem, whatever its scope, is the lack of more general recognition in the Wikimedia community of its seriousness.
There are a few ways that the problem can become high profile enough for everyone to think about it and take it seriously - the most obvious is publicity following an attack of some sort, but another method can be pointing out to people and the community when serious problems are overlooked by people known for their judgment and awareness. It demonstrates that stalkers and those whose history includes cross-project harassment can be easily overlooked and even praised because we don't have an organized way to track them, maintain a consolidated history or deal with them across the larger community.
