The idea here is that the solution to a potential controversy is to get rid of the ban on categorizing posts, clearing up bugs and opening up the game. I would argue that our core posts should be in play for hierarchical and webbed categorization. Banning official posts from being in any other official category not only generates bugs, but prohibits all sorts of interesting and good ideas. It is not only impractical, but unwise to universally prevent posts from being in multiple categories. While scams may be possible using certain combinations, dangerous combinations should be banned specifically. Do we really want to prevent all rules which classify official posts?
