Review bombing of Top-rated episodes

There have been some toxic internet communities of the show One piece who have been bombing the ratings and reviews of the latest Attack on Titan episodes, by deliberately rating them 1/10 despite not having touched the show. More so, They have been creating multiple fake IMDb accounts to do so (they publicly boast about these on twitter). Things got uglier last episode, when Breaking Bad fans started bombing episode 78 of AoT, because some groups have been falsely rating the highest rated TV episode Ozymandias (I don't exactly know how this started) as it has dropped from 1st to 14th top rated TV episode. Naturally, the toxic one piece fans I mention of joined the fray soon enough, and as of now ep 78 of AoT stands at 9.7/10. Definitely doesn't sound bad, but given how much excited and impressed fans were with this episode, so much so that it was 10/10 for one day, before being affected by the bombing, its not fair. And the result is not one sided. Fans of all 3 shows have been falsely rating each other to retaliate, which is pathetic

Honestly, behavior like this sucks all the fun of episode ratings, as there's no integrity left to it. I request IMDb to look into this and solve it. Thank You.
