Possible abnormal rating activity on Attack on Titan episodes

Hello IMDb Team, I would like to report a possible issue with the ratings of two episodes of Attack on Titan. I have evidence (screenshots) showing that these episodes had a stable 10/10 rating for a long period of time, but then suddenly dropped to 9.8 without any clear reason or visible changes in the review volume. This sudden drop suggests potential abnormal voting activity (review bombing or coordinated voting). I kindly request that you investigate the recent votes and apply your Weighted Rating system or any other appropriate mechanism to ensure fairness. Thank you for your time and commitment to keeping IMDb ratings fair and accurate.
