Hostelworld ratings.

It's not worth trying to falsify your ratings. This from HW in their last newsletter:
"The hostel ratings are critical to our business and to your business, the hostelworld.com ratings and reviews have become a benchmark within the hostelling industry and we are very proud of this. We know how hard most of you work throughout the year to maintain high standards, we also know that it’s hard to please all of your customers all the time however, we would like to remind all of you the importance of genuine voluntary ratings. We have removed a number of rating bars in recent weeks because of disingenuous reviews and we also have a number yet to contact, some hostels will also be removed from the site permanently.

So to reiterate, fake bookings will not be tolerated, at the very least you will lose your ratings bar and at the very worst we will remove your listing from Hostelworld.com and our affiliated sites."
