But that isn't the standard that was used. It seems to be something more akin to 'don't not moderate content that encourages...'. Except it isn't quite clear what moderation is considered good enough, as one can look at other sites which hosted and continue to host similar content. Sure, they haven't taken the stance they won't moderate, but they haven't done enough to moderate the content to remove it. Or is it that stance? Perhaps that was the defining standard, that they took a stance instead of passively allowing it to remain like other sites do (until called out, at which point they'll react based on the size of the call out).
