Whether to include a 'criticism' section and what to put in it can be solved reasonably easily by applying the editorial judgement of editors of good faith to the question: does it serve the readers of the article?
It's pretty clear in the xenisucks.com case that there are POV pushers trying to shove anti-advocacy into the article, and never mind the interests of someone who reads the article because they want to know about Xeni Jardin; the thing to do in this case is to deal with them as we do any POV-pushers. We don't need any new rules, policies or guidelines.
