There's another issue at play too.
The site isn't free, at least it's not free to the advertisers that is.
It works like this, Google places banner ads on the page, but the ads themselves are tailored to each computer that loads them based on browser history and a bunch of other stuff. Then, park management wanting to promote their park direct people to the site to show prospective campers how great the place is, based on third party opinions. For that to continue, controversy and anything potentially litigious is not allowed.
So, the bottom line is, more 'happy campers' online equals more hits, more hits equals more traffic, more traffic and less controversy equals higher Google rankings, higher rankings equals more advertising revenue.
The almighty buck.........
