If we are going to have the exception to the norm at all, then there has to be a pretty high standard of evidence to prove that adding ‘Y’ to the discourse, in fact, has bad consequences.
I want to note that LW definitely has exceptions to this norm, if only because of the boring, normal exceptions. (If we would get in trouble with law enforcement for hosting something you might put on LW, don’t put it on LW.) We’ve had in the works (for quite some time) a post explaining our position on less boring cases more clearly, but it runs into difficulty with the sort of issues that you discuss here; generally these questions are answered in private in a way that connects to the judgment calls being made and the particulars of the case, as opposed to through transparent principles that can be clearly understood and predicted in advance (in part because, to extend the analogy, this empowers the werewolves as well).
