Not completely understanding you, Gary. When you say your accuracy rating was altered, do you mean Airbnb lowered the star rating you were given, or did they just tell you to pull up your socks (for being awesome...).
If it was just a message telling you that you should be more accurate, you can ignore it. It was an automatic mailing. If a star was knocked off, I'd be surprised, but then I am surprised quite a lot by the site these days. Will you let us know?
If it is serious - affecting your rating, threatening penalties - get on Twitter, whether you like Twitter or not, and send a direct message to AirbnbHelp.
