Where can I report unfairly marked ratings? Also why doesn't IMDb give a proper adjustment on the ratings when it comes to Kdramas?

IMDb gave adjustments when both Cleopatra documentary from Netflix and Little Mermaid remake were bombarded by 1 ratings. However, the same adjustment hasn't been applied to this kdrama, King the Land.

If you look at the ratings of the show from the link above, 96K people from saudi arabia rated 1 out of total 125K. This is obviously targeted rating. If you check the reviews, you can find 2 main reasons why they gave 1 ratings. There are 2 episodes featuring an arab prince who wants to have a business in south korea. The arab prince is played by an indian actor who was a popular supporting actor in Squid Game. People are giving 1 ratings because an indian actor who has a darker skin tone plays an arab prince. They are also giving 1 ratings because the arab prince was being fallen in love with a korean lady. These are not the right reasons for contributing 1 or any ratings, and again those segments are only featured in 2 episodes out of 16. I was thinking that maybe it's going to be fixed like Cleopatra and Little Mermaid later? But it doesn't look like it's going to happen any time soon. I wanted to report about it, but there's no any button I can click to process. I don't watch a lot of kdramas, but I experienced this kind of wrong ratings on some other kdramas. IMDb should not protect the ratings of american movies and shows only. Also they should they have a report function to report "usual rating behaviors".
