Okay, now some serious responses:
@Pandora said in Intersectional MU* Community - Discussion:
[Things] that happens outside of a game's in-house systems (mail, pages, messenger) is nearly impossible for staff to police.
Even things on-game are difficult to police. An experienced staffer (or someone who can see the shape of things instead of the literal nature of things) can use the same methods of managing problems based upon on-game behavior as off-game behavior.
We (Emmah, Troy and I) did this on The Reach twice. Once it even stuck. 
When this is okay to do is an entirely different question. We're not talking about a game, here; we're talking about behavior to and about "intersectional" issues on a private chat server. I'm imagining Wora For Non-Straights. Its own rules can easily straightjacket its ability to have honest discussion about difficult or contentious issues, or to have discussions with high-strung personalities.
IGU kind of worked, but they did get caught in the loop of defending its own rules against otherwise reasonable, if sometimes snarky, discourse. Not as bad as Electric Soup; that place ate itself in months.
You're now accepting the burden of being yet one more place where vulnerable people are wearing a target on their back without the protection of staff aid should things go pear-shaped
This is a very subtle and interesting point: Kestrel has designed a discussion group around people who see themselves as vulnerable. Some vulnerable people do lash out when they feel attacked, making the pear all on their own.
Personally I think the answer is to say this: "We are here for X reason, and to discuss X in a reasonable manner."
Or as Kanye brought into the Soapbox vernacular a while ago, "We don't do that here." Just with a follow-up as to what we do do here.
Do do.
Scooby dooby doo.
It pains people like me that Soapbox doesn't have a more clear focus than "eh, whatever, just don't burn the place down", but that's Soapbox. IMC (I'm calling it "IMC" now) has a much clearer purpose. I can see, like Surreality and others, that the rules of the community can stop the administration from maintaining it, but we also forget the #1 rule of any private group: My group, my rules.
Which is why Tempest got a million upvotes for questioning Kestrel's personality.
Because no matter the rules, this hobby has proven over and over and over and over again that the rules don't matter compared to the administration enforcing them.
