review bots
Strange distribution of ratings on episode one of Oshi no Ko, which is extremely likely to be caused by bots. There are a lot of 8, 7, 6, 5, 2, and 1 ratings, and looking at the ratings by country shows how strange the distributions are. The country with the most ratings is Colombia, and it essentially only has 8, 7, and 6 ratings and a small amount of 10 and 9 ratings, which are likely to be legitimate ones as they match what the episode’s total weighted mean used to look like. The unweighted mean is 7.1, while the weighted score shows 6.8, so the weighing system likely allowed the fraudulent reviews to pass but not the real ones. The bots are probably also not exclusive to Colombia as you can still see the trend of 8, 7, 6 and some 5 ratings from other countries.

Hi Hi736-
Thank you for bringing this to our attention.
We are aware that there are people who may vote for the sole purpose of trying to inflate/deflate the rating for a movie. We have several safeguards in place to automatically detect and defeat this type of ballot stuffing: even though we count and display all unaltered votes in the rating breakdown, we apply several countermeasures against all attempts to skew the rating for the weighted rating you see displayed on the site. We will review the title in question to ensure that the weighted average is displaying as intended.
For more information on our abuse detection methods, or details about IMDb ratings and weighted averages, please refer to our Ratings FAQ.
Cheers!
