How to deal with trolls bombing episodes with 1 star ratings?

Hey there, I noticed a recent issue where it seems trolls have been mass voting certain shows with 1 star ratings. It's happened this past week with two very popular anime, Attack on Titan and Demon Slayer, where around 15% of the ratings for the newest episodes are 1/10. This is far above average looking at past episodes and it's been brought up by many of the reviews, which are mostly positive. While I realize a rating is just a number, myself and many others look to this site to see what movies/shows are worth watching and how new things are being received. Are there moderators to look into or fix issues like these? Because otherwise, knowing that ratings on the biggest internet movie site can be manipulated so easily makes me question relying on it.
