WTF. I'm not sure why you think someone saying "I was sexually assaulted at this resort" is somehow against that section of the policy.
As bleak a reading of that clause that this is, you can say if you are the victim of an assault you were a participant in that event participant (albeit an unwilling one), and the review must be removed.
My broader point was simply that this isn't a new interpretation of this policy, they've been doing this for years.
