The “solved” problem of Attack on Titan’s review bombings?

Quick context: review bombing for some animes going on, aot was/ is being heavily targeted but the thread for this was considered solved.

The mods say that their system is working and there does not need to be further action, but seriously how does this make sense? When episodes are clear as day dropped from the top 10 positions of all episodes to the 50-70th positions surely that means the weighted mean is being affected by the review bombing.

Surely the simplest solution would be to remove all ratings on aot in the past 7 to 10 days, this would get rid of all the review bombing as well as all the inflation from fans trying to prop it back up.

Am I missing something on how the system works? Is there some sort of biweekly cleanup or is this “system” just the weighted mean.

I’m not trying to be rude or toxic but I’m just genuinely confused.

Thanks.
