Here is an example of the coordinated downvoting https://hackertalks.com/post/8692093

Of course its a controversial user who got someone angry enough to automated downvoting @[email protected]

But you can see every post they make gets 53ish downvotes from these two instances, plus some organic ones after a few hours.

A individual user airing their personal biases and manipulating lemmy isn't good for the community, regardless of how you feel about their target. This is a really bad thing (tm)

lemmy . doesnotexist . club is where all those Nicole pictures are linked from for some reason.

what does defederated mean?

like trusted instance admins to block untrusted ones (like the ones in the post) from showing all content/interactions on the trusted instance so users dont interact with them - like server block?

[–] [email protected] 9 points 1 month ago

Yep, exactly that. It's a little more complex, thus the different term (defederation), but from user-perspective it's exactly that: a server block.

@[email protected] I think this is something you should look at as SJW is under the federated list

[–] [email protected] 2 points 1 month ago* (last edited 1 month ago)

Right now the second link returns errors. Probably that instance is down.

[–] [email protected] 4 points 1 month ago

Men. Tough. I agree it shouldn't be allowed, but I can't find a shred of sympathy for Nazis.

The attacker is the admin of these two instances. Both instances have their registrations closed.

[–] [email protected] 7 points 1 month ago (1 children)

When I look, both have open registrations and don't even have a captcha? You see registrations as closed?

[–] [email protected] 6 points 1 month ago* (last edited 1 month ago) (1 children)

It could be that Fediseer is outdated. I looked at the instance's fediseer page.

https://gui.fediseer.com/instances/detail/chinese.lol

https://gui.fediseer.com/instances/detail/lemmy.doesnotexist.club

Edit: Their registrations are indeed open. Perhaps they opened it just now?

Though it is also suspicious why the owner leaves the registrations open, requires no captcha, no approval nor any email confirmation, and the admin of lemmy.doesnotexist.club has been inactive since their account creation. Seems suspicious to me.

[–] [email protected] 7 points 1 month ago (1 children)

They have both had open registrations for at least several hours. I think perhaps there's something wrong with Fediseer's detection?

Given the issues, I'm guessing these instances have been open for some time. lemmy.doesnotexist.club has definitely had a few "Nicole" accounts and some trolls.

[–] [email protected] 10 points 1 month ago* (last edited 1 month ago) (1 children)

I checked the web archive. The registrations have been open since 2023. I think it's safe to assume that the admin is indeed the one behind this and possibly also behind the nicole spam. And it has been a year since these bot accounts were created and they are still being created, the admin does nothing, does not interact with anyone, but still hosts the instance.

https://web.archive.org/web/20230809200352/https://lemmy.doesnotexist.club

We desperately need some system to fight against these type of attacks. It is still not much of a problem. Creating bot accounts and then spamming the entire Fediverse isn't hard but defending against it will be in the future.

[–] [email protected] 3 points 1 month ago* (last edited 1 month ago)

Why do you assume the admin is behind it? If you have an instance that has open registrations and no captcha, then bots will take advantage of that. It doesn't mean the admin is the one doing the attacks.

In fact, such instances are more common than they should be since open registrations with no captcha is the default configuration, last I checked 😑

This highlights one of the things that I saw as a benefit when I started on kbin: being able to see who the downvote fairies were. I know the discussion has been done to death on the Lemmy side, but as a user I found it interesting to be able to see this kind of info. For example, instead of just block/reporting the spammer, I could block their sock puppets that upvoted as well. (And did kbin.social have a lot of that towards the end. Oof.)

Thanks for digging into this.

[–] [email protected] 2 points 1 month ago

I never realized that was a kbin only thing. I just assumed my instance/mbin blocked that feature.

[–] [email protected] 21 points 1 month ago (2 children)

Lemmy currently allows mods to see downvotes, so they can fight brigading on top of admins

[–] [email protected] 8 points 1 month ago (1 children)

You mean admins, right? I cannot see downvotes on the community I mod.

[–] [email protected] 18 points 1 month ago* (last edited 1 month ago) (2 children)

Use https://tesseract.dubvee.org/

What it does look like (there were no downvotes here, but they would appear as well)

[–] [email protected] -3 points 1 month ago* (last edited 1 month ago) (1 children)

How do I use this for different instances? I'm thinking of starting an instance. Is tesseract good for any instance or just dubvee?

[–] [email protected] 2 points 1 month ago

It can connect to any instance

[–] [email protected] 7 points 1 month ago (2 children)

That’s pretty neat to have as a mod. But I don’t think it should be readily available for any average Joe.

Sometimes people are looking for anything to get angry about, myself included. And I really don’t want to get into a slap fight with someone whose dick pic I downvoted.

[–] [email protected] 9 points 1 month ago (1 children)

The data itself is public, clients just don't show it. Imo clients should add that capability, the lack of privacy is better than the illusion of privacy.

[–] [email protected] 5 points 1 month ago (2 children)

It's not exactly public, IIRC? Like, admins/mods have access, so it's not private by any means, but I wouldn't really call it public.

[–] [email protected] 2 points 1 month ago

Anyone can set up a server, make themselves an admin, and federate with other servers. That's what makes it decentralized.

[–] [email protected] 6 points 1 month ago (1 children)

https://github.com/LemmyNet/lemmy/issues/4967

Due to the way federation works, it is public. Anyone could spin up an instance and make a tool to make votes public.

[–] [email protected] 5 points 1 month ago (1 children)

That's what I meant by admins/mods, thus I still think my point is still valid: not private, but not exactly public.

[–] [email protected] 2 points 1 month ago

I think it would be better to make it clear that people's votes can be seen by anyone with a little technical skill, better than hiding that fact.

[–] [email protected] 5 points 1 month ago

Indeed, which is why it's limited to mods

[–] [email protected] 8 points 1 month ago

Visibility is a good thing.

[–] [email protected] 10 points 1 month ago (1 children)

There is some interesting area here, like a personalized vote score, based on others who vote similar to you, giving them more weight then people you never agree with.

net-net I think open votes make for better neighbors.

[–] [email protected] 8 points 1 month ago

PieFed has some interesting thoughts along these lines.

I actively expect to never see such a thing in Lemmy though.

[–] [email protected] 10 points 1 month ago

Great work. It doesn’t matter who the target is this time (pretty sure I blocked them every time they popped up with a new account). This kind of shit should not be tolerated at all.
