The language here seems off. (1) If the allegation is true (I can’t tell?), then wouldn’t this be anti-tampering/manipulation?

(2) Fortunately there is already a way to defederate from a single community somewhere on the Threadiverse, it’s called blocking it. With fewer than 100 monthly active users and less than one post per day (or even week?), I bet it would barely be noticed by OP?

(3) For anything more, I would need additional information such as whether the downvoting patterns were all delivered within seconds of one another, as some poorly written implementations of actual vote manipulation sometimes do. Otherwise it is just one person’s word, based on incomplete information, against another?

(4) All of that said, again, the argument for vote manipulation does not seem to hold water to me. There are only 9 total weekly activity users for that community!!? 79 monthly users, fewer than 100 posts total, and the vast majority are made by one of the mods themselves. This is a TINY community, barely a blip in the wider Threadiverse, where the phrase “struggling to survive” might very well apply.

I hate to bring up Reddit, but back on the bad place, I REALLY hated it when serial downvoters would be extremely obvious like going down through an enormous weekly mega thread and downvote literally every single comment in it, plus also do the same in every other post as well. The timestamp of when it started and stopped was super easy to see - a single, hard cutoff in each case where every single comment before that had received a downvote, whereas every single comment after that point had not. In the community, we all joked about who we had managed to piss off so badly that they would bot brigade us in such a manner. But it was also quite irksome, especially to new members of the community that would seemingly get slapped in the face upon asking an innocuous question and then wonder why “our” community was being such a dick as to immediately downvote them (WITHIN SECONDS of posting), and then never follow up with any explanation as to why. I mean, it was even called a “question mega thread”… so if they were invited to ask, then why downvote them for doing as asked?

Anyway, this instance has the right to protect itself against not merely a handful of random downvotes but by serial downvoting brigades, such as possibly delivered by a bot brigade. Mind you I don’t know that that is what is happening here, but given the other issues seen in this post (calling to defederate from an entire instance for behavior observed in only one singular, tiny community? and the instance itself is fairly tiny to boot, only 90 users per month, yet highly thought of with 13 endorsements for all that), I am not ready to simply believe it.

But please feel free to discount my opinion as I do not and never have had a lemmy.world account.
