if I wanted to bring the Fediverse down or at least keep my customers from going there, I would sow this stuff as much as I can

Agree. And that's been my experience here too. I made two posts critical of reddit and they each seemed to have been astroturfed by toxic reddit shills.

I think it would require a lot of active and dedicated mods and admins, which I'm doubtful is doable. I don't know that there's a fix for this but a "true block" (instead of the current "mute") might help; but there are major downsides to that type of feature as well. I wrote in a blog that it might require an advanced AI to moderate everything.

Yeah we should have ignore and reporting lists that is on an invite only basis, which then can be shared by users of said list. If you didnt get invited then you should be able to copy a users reported/ignored list to make the whole fediverse more palatable. Each bunch of list users can then cross reference each potential bad actors. Then each month each admin could implement a ban of thoses accounts and perhaps try to filter new incomers.

Totally true. I made a totally reasonable comment about a month ago (stated that women shouldn’t be hit on at the gym by randos), and I got downvoted to oblivion and the comment was spammed by 7 different users who essentially acted like I was Hitler. Then they started spamming my comment history and I had to delete all of my old posts.

Seemed like a real person was behind it, but may have been using bots to spam me.

Just so everyone is aware, this is the thread OP interpreted as so abusive it would warrant banning this person across multiple instances.

In this thread, you’ll notice that another user dares to disagree with haui_lemmy. haui_lemmy interprets that as trolling, and goes on a crusade to purge the entire lemmyverse of dissent.

As the fediverse becomes more and more of a feasible alternative to corporate social media, it will be inevitable that trolls and spammers will use our platform for malicious things. All we can do is to get better at moderation, maybe somehow bust these farms.
