I discovered this after upgrading our instance yesterday, which also upgraded all frontends to their latest versions as well. After I did, our Tesseract frontend stopped working and I noticed immediately as it's been my primary for a while. Initially I thought it was an API version mismatch, but no, it was much worse.

Someone pointed out that the developer of the frontend added an explicit hidden and unmodifiably blacklist which includes any and all instances to the left of Kissinger. There's a commit which also explains their specious reasoning about our instance specifically, as it seems we've been on their shit list for a bit longer than that.

This instance and its admin staff encourages identity politics, groupthink, mob mentality, and extremist solutions to societal problems. Users who advocate violence are not moderated so long as the admins agree with the target. Caution and critical thinking are advised when interacting with this instance or its users.

When you use tesseract to connect to one blacklisted such instance , you just get a message informing you that Tesseract is "incompatible with that instance" which leads one to think of a technical issue, like an API mismatch, rather than the dev being an opinionated coward.

Isn't it funny how all the software developed by turbolibs, like Piefed and Tesseract, end up with hidden control mechanisms from developers who think they know better than everyone else? That they don't just think they deserve to tell you what you should think, but they should manipulate you to think it? Isn't it funny how libs go on about how bad it is to support lemmy due to the ideology of the devs behind it, and yet lemmy has 0 opinions as a software? It does make one think...

Anyway, I forked - it as one does - and disabled the blacklist, but since this is a massively ideologically compromised software, I'll doubt I'll keep this frontend up after Lemmy 1.0. I think we'll bring up mlmym again now that someone's maintaining it again.

Doesn't piefed also do OCR on every image to try and detect if it's a 4chan screenshot and then pretend it had an error when uploading? Sneaky lil shits.

[–] MonkderVierte@lemmy.zip 10 points 22 hours ago* (last edited 22 hours ago) (1 children)

Tesseract is a Sublinks/Lemmy client designed for media-rich feeds and content.

Because you mention OCR; people seeing this: it's not the OCR tool.

Thanks for clearing this up, I've never heard of the Lemmy ~~client~~ frontend Tesseract and was very confused.

[–] Nindelofocho@lemmy.world 8 points 1 day ago (2 children)

I keep hearing so much shit that piefed does but also see a ton of people either ignoring it or praising it. Does piefed have some sorta propaganda team or something?

[–] Corkyskog@sh.itjust.works 4 points 23 hours ago (2 children)

And here I am, going WTF is a piefed?

[–] Nindelofocho@lemmy.world 1 points 5 hours ago

It’s where you are Fed a Pie

[–] Sandbar_Trekker@piefed.zip 4 points 18 hours ago* (last edited 11 hours ago) (1 children)

It's similar to Lemmy, but with more features and has better integration with Mastodon.

- Edit -
Some specific features that PieFed has:

  • Support for Posts with Polls
  • Ability to follow users (including Mastodon users that aren't specifically tagging a community in the threadiverse)
  • Feeds (combine multiple communities into a "feed" )
  • If a post has been cross-posted, comments from every community are shown/organized below the post.
  • Post/user flairs

Downvoted for helpfully answering a question, only on ~~Reddit~~ Lemmy.

[–] Sandbar_Trekker@piefed.zip 2 points 11 hours ago

Yeah, it happens. ¯\_(ツ)_/¯

I probably could have been more helpful by listing out some specific features, so I went back and edited them in.

[–] OpenStars@discuss.online -3 points 14 hours ago (1 children)

It does not help that for that issue, as too for this OP, a lot of misinformation is spread, which obfuscates the truth.

e.g. in both situations, people claimed that something was hard-coded when in fact it was not.

That doesn't mean that PieFed isn't actively censoring content (it is, and misleadingly so too), or that you should use it (use whatever software you want), but it does mean that the people criticizing it, having cited that specific "alternative fact", were spreading lies. Probably without realizing it, yet they certainly don't seem all that concerned about actually reading sources in order to find the truth. Which, yeah, complicates people's decisions about what services to use.

[–] mathemachristian@lemmy.blahaj.zone 2 points 12 hours ago (1 children)

There is a very much hardcoded list of instances that determine whether a piefed instance is considered to have a good "defederation policy" or not.

[–] Sandbar_Trekker@piefed.zip 1 points 11 hours ago (2 children)

As far as I understand it, it's not "hardcoded" in the sense that all piefed instances have it (otherwise I wouldn't be able to respond to you).

From what I understand, there is a default list, but this can be edited by any instance admins.

[–] mathemachristian@lemmy.blahaj.zone 2 points 4 hours ago* (last edited 3 hours ago)

No! There is a hardcoded instance list to determine whether a piefed instance is considered to have a good “defederation policy” or not. All piefed instances have this if they didn't fork the code.

https://codeberg.org/rimu/pyfedi/src/commit/881a5c95657b03c29e81ac8f619e4d26e4f6973d/app/templates/auth/instance_chooser.html Line 562

       // Handle federation status
        const watchedDomains = {
            'hexbear.net': 'hexbear-status',
            'hilariouschaos.com': 'hilariouschaos-status',
            'lemmygrad.ml': 'lemmygrad-status',
            'lemmy.ml': 'lemmy-status',
            'gregtech.eu': 'lemvotes-status',
        };
        
        const defederatedDomains = instance.defederation || [];

        countDefederated = 0;
        
        Object.entries(watchedDomains).forEach(([domain, elementId]) => {
            const statusElement = document.getElementById(elementId);
            const isDefederated = defederatedDomains.includes(domain);
            
            if (isDefederated) {
                countDefederated += 1
            }
        });

        if(countDefederated >= 3)
            defederationQuality = 'Good';
        else if(countDefederated === 2)
            defederationQuality = 'Ok';
        else if(countDefederated === 1)
            defederationQuality = 'Minimal';
        else if(countDefederated < 1)
            defederationQuality = 'None';

So you could defederate the "tankie triad" but not hilariouschaos.com, lemmychan and whatever else harmful instances and be considered to have a "good" defederation policy. This is what is shown to new users to make a decision which instance to join but it is impossible to find out on what basis this grade is assigned except for diving into the code. And it cannot be altered except for forking.

Precisely. We could point people to the very dictionary definition of the word, but it seems not to change many people's mind who have already decided which "camp" they want to be in, and that they will (attempt to) preempt the word to mean... whatever they feel like.

Hard coding is the software development practice of embedding data directly into the source code of a program or other executable object, as opposed to obtaining the data from external sources or generating it at runtime.

Hard-coded data typically can be modified only by editing the source code and recompiling the executable

Therefore, a statement like

IF (instance-set-variable) THEN
{
... implement block
}

is by definition not "hard-coding", bc it asks the instance admin what value it wants for that variable, and then only conditionally runs the code to set the instance block if the admin asks it to.

There are plenty of things to criticize PieFed for, but "hard-coding instance blocks" is not one of them. (And now it seems the same error was made regarding Tesseract.)

[–] db0@lemmy.dbzer0.com 3 points 2 hours ago (1 children)

The same error was not done regarding tesseract. It absolutely hardcoded instance blocks.

[–] mathemachristian@lemmy.blahaj.zone 1 points 1 hour ago* (last edited 1 hour ago) (2 children)

apparently there is some env var PUBLIC_ALLOW_TOXIC_MODE that disables the entire list. From https://github.com/db0/tesseract/blob/c6767607da9f08033bbc38c2c3e38975be0eef2e/src/lib/policies/system.ts#L89

export async function updateSystemFilterPolicy() {
    SYSTEM_POLICY.set(BLANK_SYSTEM_FILTER_POLICY)
    return
    if (SBDisabled && get(userSettings).enableToxicMode) {
        SYSTEM_POLICY.set(BLANK_SYSTEM_FILTER_POLICY)
        return
    }

dunno if it actually works as intended tho. Also the main repo got deleted apparently lmao

[–] db0@lemmy.dbzer0.com 3 points 1 hour ago (1 children)

Also the main repo got deleted apparently lmao

Forgot: They didn't delete it. They renamed it then reversed its history to 2023 so that I can't sync any more changes to my fork and my commits telling him to eat shit are not visible in the repo diff. lol

[–] db0@lemmy.dbzer0.com 3 points 1 hour ago (1 children)

Yes for the second blacklist, if you knew that you were getting things filtered out in the first place and if you knew to look for the setting and find it.

But the first blacklist, the one I discovered, which prevents you from even using an instance whatsoever, is completely hardcoded with no way to bypass.

ah thanks for the clarification

[–] mathemachristian@lemmy.blahaj.zone 0 points 4 hours ago* (last edited 2 hours ago)

Please see my comment spelling it out in detail https://lem.lemmy.blahaj.zone/post/45697068/21461570

but it seems not to change many people’s mind who have already decided which “camp” they want to be in,

this is also a very backwards telling of events when people keep calling us "tankies" and "stalinists" or whatever whenever someone dares to say something outside the US State sanctioned lines about foreign policy.

[–] GoatSynagogue@lemmy.world 9 points 1 day ago

They also block every source that doesn’t agree with the main devs ideology and politics.

Oh if they do that's great, the main dev of piefed went on a hissy fit because other instances used AI tooling, for them to be doing the same is just perfect. Gotta love hypocrites
