To be fair, I've always found the idea that someone can post a handful of papers and get the broadcasting power of every waking person on the forums seeing their notice -- Legal, or illegal, to be a disproportionately powerful tool for creating drama in roleplay. If I could have my way, I would have all IC communications kept strictly IC through either the constant placement of actual notices, or through noticeboard systems and to no longer permit such notices to be placed on the forums.
If regulating posting these notices through the boards puts a strain on the ability for someone to use a tool as powerful as a universal public noticeboard system that can directly influence public perception for the low-risk effort of dropping a notice anonymously in the corner of the Ouvrier, or somesuch. The world needs to be constrained a bit from using Mistbook to either slander, publish illegal papers, or -- You know, whatever controversial documentation goes up there, because even if it is taken down, the post does remain long thereafter and it isn't uncommon for someone to have roleplayed as having seen said notice, even after being torn down, because it at one point existed; Nor is there a way to police it.
So if this whole thing is in a step in that direction? I'm all for it. Port-a-Lucine Mean Girls gossip rags and other political commentary issued without a publisher and reaching a broad audience beyond whoever comes across a pamphlet has lead to a lot of silly roleplay in the past, when it should be a more uphill battle for unpublished, unsupported, and unregulated pamphleteers to distribute their documents to a broader audience.
