You have to realize the reason Touhou was insufferable was the same reason /jp/ sucks shit right now.
It's a small - underaged - collection of moefaggots who won't shut up about their goddamn fandom. Most of the Touhou fans hate them, but they're ever vigilant and vocal. They complained to moot and since moot is so removed from /a/ because of that shithole /b/ eating up his time, he had no idea of the delicate situation in /a/ and made a decision based on bad information. Hence why /jp/'s material is so arbitrary given what was once /a/ - hell, moot all but banned Fate/stay night, a milestone in /a/'s history, from every being discussed here again because anime discussions invariably descend into visual novel ones, which get insta-deleted by janitors and mods hoping to avoid shitstorms about what belongs in /a/.
While I hated the creation of /jp/ and still find it one of the worst boards on 4chan, moot can only be blamed for the lax moderation of /jp/ - Touhou should be STERNLY controlled there, it is General Japan not "Project Shrine Maiden for Newfags", the board should BAN Touhou and cut away all the cancer from this imageboard.
I love Touhou but sorry, /jp/ is a blight that must be dealt with.
