The guild is a good idea in terms of moderation but a bad idea in general, it would only serve to create an insular environment where only the old regulars participate.
Why? I think the bigger issue would be "who's moderating?" It can't be everyone and if it's only one person you'll inevitably get "XXX is biased against me politically, that's why my post was deleted/hidden!" Random people can still find the place, just like they find this one.
