Good Reviews Removed Suddenly from a New Movie

Hi,

There is a new movie that was released in cinemas about 2 weeks ago that had 27 reviews, 6 good reviews were removed today all of a sudden, is this a glitch from IMDb or were the reviews removed due to false reporting? I read them last week and today they suddenly disappeared. The artist that has issues with some crazy people removing their titles, pics, plots, trivia section completely deleted and other issues that your team helped to fix is the same artist facing this issue now with their new movie released. Please help and clarify the situation. We are really tired of things like this happening.
