This page shows, for each user, how many of their posts were deleted by the staff.
(users with less than 2% of deleted posts aren't shown)
If you are in the green part, you are fine, but try to be a little careful.
If you are in the orange part, you should really improve the quality of your posts.
If you are in the red part, you are walking on thin ice, and should think twice before posting again.
