Has anyone else noticed the obscene tags being added to new stories and recommended diaries?  It looks like the work of one or two dedicated individuals trying to troll, or at least make dKos appear "unsafe for work."  It's somewhat unsettling to see a new, moderately popular diary tagged with "penetration."

Given their complete irrelevance to the topics they're included in (obviously), I can't imagine people are adding them of their own accord.  Where do we report stuff like that?
