Add name, or delete article 

First, I think there is absolutely sufficient proof that she is who people claim she is.  Ex http://www.news.com.au/lifestyle/real-life/devout-catholic-dad-returns-home-from-afghanistan-to-find-daughter-is-a-porn-star/story-fnixwvgh-1226851020842 (for a time, this was the FIRST GOOGLE SEARCH RESULT for 'belle knox').  That link has interviews with family members who are on record with their real names.  I think that's definitive.

Second, her "privacy" should not be the concern of wikipedia.  For one, as a porn star, she is showing her body to the world; the concept of "privacy" is quaint.  If Wikipedia was so concerned about respecting privacy" wishes, and not adding anything at all unless it's 100% certain, then large parts of the Satoshi Nakamoto article should be deleted as well.

Finally, she is only notable because her real name was revealed publicly.  And if Wikipedia is unwilling to reveal her name, then this article has no reason to exist.  Delete it.

I find the behaviour of some wikipedia editors (not only reverting edits, but DELETING THEM FROM HISTORY) to be frankly Orwellian.  We are at war with Eastasia. We've always been at war with Eastasia!
