I don't think there are any points added or deducted for the owner being "downright nasty". Also, if you were to actually look at the criteria they use to score the parks, I think you will find that being on a curve wouldn't be reflected in the score of the sites. It might be uncomfortable for you, but I don't know how you could objectively say how much of a curve is acceptable for an RV site to be located next to. You said you have usually had good luck with the rating system, so it apparently works, but there are probably always going to be parks that you either like or hate that score the opposite. I would crawl through a lion's cage wearing pork chop panties to have a great lobster dinner, my wife wouldn't crawl out of bed for the same. People have different tastes in both food and RV parks.
