So I wrote a review about a hospital treatment program which was dangerous. In Yelp you can't modify your original review but you can "update" it by creating another review - or so it seems. I did this by relating my experience at said hospital with a CNN article about another hospital trying to keep their child hostage and gain control. This "update" was in 2018 and just today I received a note that my content had be flagged. "The update feature should be used to review a new experience or interaction with a business, not to revise, repost, or add detail to an existing review." So in other words, you can't modify your existing review, but neither can you create a new one showing the same pattern.
