I think it was a bad decision, and here's why. IMHO, a community isn't a library that requires strict categorization. And even in a library, you have books that focus on a subject but also discuss ancillary topics. A community is about sharing and growing and learning and having fun and being responsible and, overall, just acting as the social human beings we are. When you build a particular product, you don’t want anything impure in it as it will reduce the strength, effectiveness, longevity, etc. of the item. But a community isn’t a product.

The community was getting value from the story. That was obvious by many factors. Following such strict rules only reduces the value and cohesiveness of the community (especially as those who gained value are alienated and, thus, leave).
