Hello @saidevadiga,
it is the difference of the media (photos and videos) and reviews you did contribute versus the number which was actually published.
For all our contributions, a filter not only checks for obeying the rules, but also to prevent SPAM.
Please see How to Get In and Out of Trouble: The Main post for a good overview and let us know, if you have more questions. It is a very common topic here on Connect.
