Image uploads are now disabled on lemm.ee due to malicious users - lemm.ee

Sorry for the short post, I’m not able to make it nice with full context at the moment, but I want to quickly get this announcement out to prevent confusion: Unfortunately, people are uploading child sexual abuse images on some instances [https://lemm.ee/post/5802229] (apparently as a form of attack against Lemmy). I am taking some steps to prevent such content from making it onto lemm.ee [http://lemm.ee] servers. As one preventative measure, I am disabling all image uploads on lemm.ee [http://lemm.ee] until further notice - this is to ensure that lemm.ee [http://lemm.ee] can not be used as gateway to spread CSAM into the network. It will not possible to upload any new avatars or banners while this limit is in effect. I’m really sorry for the disruption, it’s a necessary trade-off for now until we figure out the way forward.

This is sick. Kudos to mods for dealing with this garbage. I hope the posters are all hunted down and punished.
Yeah, the admins deserve all our support on this. Not only to protect themselves as server owners, but to stop the spread. Hopefully a longterm solution will be found soon
Just like self-isolation when you have a cold - the healthy and wise thing to do.
I didn’t like Apple’s idea of scanning private images for such imagery, but I think it would be a fantastic technology to use for social media. If they open sourced it, it could help Lemmy a lot.

My honest reaction to this:

[removed externally hosted image]

bro they banned images did you not read the post lol
I think he typed up [removed etc.] as a joke

autism strikes again

I am my own worst enemy

No worries friend. I also may have interpreted it the same as you, if I weren’t already familiar with Ho_Chi’s humour.
Can I just say - wholesome :3
We had to deal with something similar on lemmygrad a while ago. All power to you for destroying these annoying bastards.
How did you guys deal with this?

We doubled the amount of mods, and banned anything remotely resembling the things on-site. Sadly many times it had to be a brave lemmygrad to check it first and take the bullet for us to report it. I was one of those people on several occasions. I still cringe at the memories. It lasted a few months iirc.I haven’t seen whatever is hitting you guys, but our bots had some recognizable features, usually hiding their spam behind spoilers or links.

It really was just a mobilization, lockdown, and purging everything that was suspicious until it stopped. That or they found a way to block those bots. I wasn’t in the command center by any means so the internal decisions I don’t know too much about.

spoilerDon’t freak out. This image isn’t hosted on lemm.ee.

Its a bug in sombodies markdown parsing.

Your URL was HTML escaped.

Correct

…?width=640&height=480

Incorrect

…?width=640&height=480

I uh… don’t know what you mean there. I was just pointing out that the image I posted is hosted externally, so it doesn’t mean I found a bypass to the disabled uploads. It displays fine on the website.
Some software had a bug in it and it broke your link, im sorry if i failed to communicate that
It’s honestly sad that some well-intentioned laws can be used to attack online platforms.
I kinda wonder though, how would go about making a law against cp but doesn’t hurt small sites like lemm.ee?

The issue is that you really can’t. The laws are written specifically to prevent plausible deniability. Because pedos would be able to go “lol a troll sent it to me” and create some doubt in a jury. Remember that (at least in America) the threshold for conviction is supposed to be “beyond a reasonable doubt.” So all the pedos would need to do is create reasonable doubt, by arguing that they never intended to view/own the CSAM.

So instead, the laws are written to close that loophole. It doesn’t matter why you have the CSAM. All that matters is you have it. The feds/courts won’t give a fuck if it was due to you seeking it out or if it was due to a bad actor sending it to you.

How is that not extremely problematic? What stops someone from using Tor and a bunch of dummy accounts to send CSAM to someone else and get them arrested?
And that’s pretty much where we are now. Bad actors creating bot accounts on multiple instances, to spam the larger (most popular) instances with CSAM.

I think they have oversimplified the situation to the point that it is wrong.

  • Arguably, Lemmy instance providers are protected in the same way Facebook or other content hosts are. So long as you are acting in good faith you are protected against any illegal content your users upload. This does mean you need to remove illegal content as you become aware of it, you can’t just ignore what your users are doing.

  • There have been cases where although a user technically ‘possessed’ CSAM, it was shown that they did so unknowingly via thumbnails or it being cached. The police do investigate where it came from. It’s not as simple as just sending it to someone and you can have them convicted.

  • Oh okay, that’s good. So if you could show that you were trying to block it, you’d be safe.

    Yes, you’d just need to show that you actively moderate/apply content policies.

    This will vary by jurusduction, but most of the West has laws similar to this I believe.

    Lemmy instances are likely already protected in many countries legally so long as they act in good faith, ie actively moderate.
    I mean, the nuclear option should be used here even if there wasn’t legal liability because that shit just shouldn’t be here.

    that shit just shouldn’t be here

    Yes, I agree. Maybe my wording suggested otherwise. But my point was that it wouldn’t be the uploader that’s punished but the instance itself. That’s kinda weird.

    Fuck the legal part, I wouldn’t want to stay on platform infested with cp. Thank you so much for all the awesome people combating this <3
    This is foul and I am extremely sorry for the users and mods who were sent the CSAM. It isn’t something they should expect to deal with in a voluntary role for their communities and it can be traumatic. I hope they are given time and space to process their emotions.
    I think this is a great move until we have something rock solid to prevent this. There are tons of image hosting sites you can use (most of which have the resources to already try to prevent this stuff) so it shouldn’t really cause much inconvenience.
    less strain on lemmy servers as well
    Quality of posts will go up too. There’s a direct correlation with (worse) quality and image posts.
    I prefer image memes, but to each their own.

    Images are grwat when used sparingly

    Guessing there’s no way to track down the uploaders?
    That would be a lot of work for admins, but perhaps reporting the CSAM to the FBI or something. I’m pretty ignorant about how that all works.
    I suppose many of them probably are posting behind VPN or Tor.
    I’m no expert on this; but I’d assume that it is sometime easy to track them down, and sometimes very hard. Easy if they just do a direct upload from their home internet with a fixed IP address, using a regular lemmy account that they also use for day-to-day stuff. But hard if (for example), they use upload from some coffee shop wifi connection with a throw-away account using some tor / proxy / VPN shenanigans.

    Thank you for the efforts you are making. This is a serious situation; more than just dealing with bad actors, you are viewing traumatic images.

    Please, for your sanity and well being, prioritize your self care. Things like this linger in the psyche much longer than you would expect.

    Thank you sir. I appreciate the dedication to the community to subject yourself to the moderation. Hopefully we can squash this before it goes too far, farther than it has anyway…
    No apologies necessary.
    Gotta do what you gotta do. Here’s hoping the culprits get a swift boot.
    its better to be safe, than to risk it with the spammers

    This might be a good thread to ask:

    Does anyone know if any of the Lemmy apps support direct imgur uploads for Lemmy?

    I remember RIF used to do that for reddit back in the day before reddit supported direct image hosting.

    Memmy on iOS uploads to Imgur by default.
    How does one disable image uploads on their server? I want to disable it for a while
    Turn off PICT-RS.
    How?

    Check out some of the posts in [email protected], people seem to be shutting down the pictrs container, removing it from the hjson config and the compose file depending on how they’ve deployed Lemmy

    I did see someone who appeared to be a lemmy.ml admin mentioning defederation in one of the CSAM threads, so if posts look old you might need to visit lemmyworld directly

    I’m sorry that you and the people on this instance are being subjected to that shit. It’s always despicable but on top of that it just seems absurd to target lemm.ee – a deliberately unprofitable platform – with such illegal means.

    And I’m honestly sorry that people are blaming & attacking you guys for no tangible reason.

    I’m surprised people have forgotten already about the attacks against lemmy.world, assumedly executed by a disgruntled ex-moderator long before we ever knew Hexbear existed.

    Instead people are jumping to “OhH it’s ThE HexBeArS” when they have not been able to freely browse you guys’ discussions or even talk with you, they’re just shown the worst take from a minority (although tbf you guys do the same on c/cth, so it’s kinda funny seeing both sides with one not realising the other is also just a human too, just with differing culture and political stance)

    Yeah, it’s kind of weird. Doesn’t whatever gets posted eventually get sent over to the other federated servers? Like every server saves a copy? Like the dumbest attack on another server would be this.

    Thankfully I haven’t seen the takes accusing HB of the recent attacks, though being accused of the attacks on .world was a little annoying. I appreciate the solidarity.

    I genuinely have no idea where this recent attack is coming from. The most fried part of my brain says “One of the big companies trying to absorb the fediverse is doing this to undermine their competition,” but I have zero evidence, it’s just the only motive I can even think of beyond it being a rogue crank.

    It’s totally conceivable that HB people would spam an instance they don’t like – though this would be against the wishes of the mods and admins – but our site culture is completely antithetical to spamming CSAM and things like that, so I don’t think even a rogue group of users would do it “on our behalf”.

    Oh, I just realized it could be one of those fash instances like exploding heads. If any were defeded relatively recently, that would make sense.

    Instead people are jumping to “OhH it’s ThE HexBeArS” when they have not been able to freely browse you guys’ discussions or even talk with you, they’re just shown the worst take from a minority (although tbf you guys do the same on c/cth, so it’s kinda funny seeing both sides with one not realising the other is also just a human too, just with differing culture and political stance)

    I don’t think I have much to contribute to the “both sides” thing that is useful, but I’m going to talk anyway because I’m thinking about it now.

    off-topic

    I think if you asked a hexbear user to seriously answer how representative those screenshots are of lemm.ee, they’d probably say that lemm.ee is much more ideologically disjointed on a handful of issues, especially regarding history and geopolitics, and the screenshots are only representative of some of the more annoying tendencies among the neoliberals and poorly-educated “anarchists” (like that dude who decried “tankies” and used Sankara as a counterexample, when we all like Sankara). I also think they would be correct in saying this. I don’t know what the anti-HB people who don’t comment on our instance think, I hardly ever see it, but I can at least tell you that we know much more about neoliberal ideology than they do ML, because we almost all started out as de facto neoliberals and nearly none of them have even a basic understanding of ML theory (which is not really their fault, to be clear).

    Anyone on any instance federated with hexbear is welcome to post questions to c/askchapo. If they are relatively polite and not presumptuous, we’ll be happy to answer. If people are still mean, report it. You can let me know and I will personally nag the mods to address the matter properly. Just recently we had a thread from a .ml user who wanted us to state our opinion on Trump for the record for the hundredth time, so about a hundred users chimed in that they all hate his guts (I also made a comment to that effect). We’re happy to discuss things openly and it would be good for us to improve community relations to avoid things like one group accusing the other of doing something as heinous as what the OP describes.

    To be fair, some of the rhetoric you all use makes your political compass difficult to navigate.

    As I said, the question is welcome no matter how tedious I might personally find it, just like any question asked in good faith.

    Complete aside: polcomp is a bad way of attempting to understand politics. It has no way of understanding Marxism.
