I own the "everything-list" Google Group, which has no explicit moderation policy, although I do block spam and the occasional completely off-topic post from newbies who seemingly misunderstood the subject matter of the forum. It worked fine without controversy or anything particularly bad happening, at least in the first decade or so of its existence, when I still paid attention to it. I would prefer if Eliezer also adopted an informal but largely "hands off" policy here. But looking at Eliezer's responses to recent arguments as well as past history, the disagreement seems to be due to some sort of unresolvable differences in priors/values/personality and not amenable to discussion. So I disagree but feel powerless to do anything about it.
There is a large difference between running a private list and a more accessible forum associated with an organization (the logos on top).

This is my attempt to codify the informal rules I've been working by.
I'll leave this post up for a bit, but strongly suspect that it will have to be deleted not too long thereafter. I haven't been particularly encouraged to try responding to comments, either. Nonetheless, if there's something I missed, let me know.
