Attack on titan being heavily downvoted

Dear IMDB,
Since the past few days, an individual has started a huge intentional online campaign to downvote all the highest rated Attack on titan episodes. He has ammassed all of his followers and friends to create fake pretexts to heavily bombard all the 9.9/10 and 9.8/10 rated Attack on titan episodes. Unfortunately, all of the highest rated Attack on titan episodes have dropped from 9.9/10 to 9.8/10 after thousands of 1/10 and 2/10 intentional ratings. The overall Attack on titan rating has also dropped from 9.1/10 to 9/10. IMDB must do something about it as it is affecting so many fans worldwide and it is also directly affecting the credibility and reputation of IMDB. We kindly and urgently ask IMDB to restore all the ratings and to grant a special rating protection to Attack on titan as it is currently subject to heavy downvoting. Please take any action necessary as it is urgent and serious. Thank you for the support.     Kind regards
