About half of lemmy today

Tesseract is a web client for Lemmy that was found to be secretly and arbitrarily blocking users, communities and even entire instances. You can see if you're one of the kool kidz by running

curl -s https://tesseract.dubvee.org/tesseract/api/system/policy | base64 -d | gunzip > policy.json

and grepping your name / instance. Further details can be found in this post.

The poem above is adapted from Bertolt Brecht's The Burning of the Books, which can be read here. If you would rather read it in the original German, go here.

I’m hard-coded into both Tesseract and Piefed.

Get yar medals here!

For the lucky ones indirectly blocked by Tesseract (instance ban / regex):

For the elite few who pissed them off enough to be banned by full name:

IMO first and second class should be reversed because being banned by regex implies the guy cared enough to make sure he got all your alts.

emergencyfood@sh.itjust.works · 3 pts · 25d

I don't think that's the case. I haven't made any alts and still am regex blocked.

I know I’m banned but how would I know which one?

emergencyfood@sh.itjust.works · 6 pts · 25d (1 reply)

The list has been mirrored at https://file.garden/amIRhTctI0qld2r5/policy.json

You aren't banned by name, only by regex :-(

Ty!

davel@lemmy.ml · 5 pts · 25d (1 reply)

Most of the regex bans are for those with user accounts on multiple instances under the same name. Extreme example: https://lemmy.ml/search?type=Users&q=cm0002

JSON isn’t especially greppable, which is why I often pipe them through gron.

goferking0@lemmy.sdf.org · 1 pts · 25d

Did that user even make the list like on piefed.

Weird how it's never the tankie instances doing the most blatantly authoritarian shit on Lemmy

Arcanepotato@crazypeople.online · 13 pts · 25d (1 reply)

It makes no sense because some A+ comrades are not blocked but I am? It must be the veganism.

Edit: oh darn, another comment says it's likely because I have the same username on different instances. I thought that was the least shady way to do things?

Some of us don't know how to use computers and didn't realize how the fediverse worked at first 🥲

Edit: I hope it was one of these

eldavi@lemmy.ml · 2 pts · 25d

... didn’t realize how the fediverse worked at first

Same here and all if my accounts are easily regex-able so the hard coded blocks definitely have something to do w your ability to be received by the normies.

9point6@lemmy.world · 12 pts · 25d (2 replies)

This is a bit of a misread from where I can see

There's more people upset about not being on the list

raspberry_confetti@lemmy.ml · 7 pts · 25d (1 reply)

We just have to post harder

CultLeader4Hire@lemmy.world · 3 pts · 25d

WAKE UP SHEEPLE!!

carotte@lemmy.blahaj.zone · 9 pts · 25d (1 reply)

"^carotte$" is in the user regexes but i'm not in the user list... hmmm.

looking at the list i'm wondering how is it possible that any content from lemmy showed up on tesseract lol. why did they block "article is paywalled"???

VeldtSchema@lemmy.ml · 4 pts · 25d

Because the loser behind this hates people that are not okay with the enshittification of the internet, of course!

The whole thing screams he is not okay with conflict-So he hides anything that he considers conflictive. There is no war in Ba Sing Se moment.

Edit to add: He’s put it back up again 🤷


Wow. Guess what existed yesterday but not today?

I was about to show how the repo version and the dubvee version of the obfuscated banlists are somewhat different from each other, but it’s no longer possible now that the repo has been deleted.

Interesting. I'm guessing the repo version is publicly viewable, but the dubvee version is the one actually implemented?

davel@lemmy.ml · 4 pts · 25d

I couldn’t say. Perhaps the dubvee version was from an earlier git commit. There’s no way to know without a copy of the deleted repo. It might be deducible from @db0@lemmy.dbzer0.com’s fork, but it’s not worth the time & effort. https://github.com/db0/tesseract

yogthos@lemmy.ml · 2 pts · 23d

lmao I love how it went from 84 to 3 stars now, I guess stars must reset when repo is undeleted?

Pandantic@midwest.social · 4 pts · 25d (2 replies)

😭 I'm too lib to be banned. I just dont post enough prolly. I didn't even know what tesseract was until today. I think I've heard of it but I almost always use the Thunder app. And I know Hexbear isn't censored for me. However, I did wonder if my instance admin was because I saw him on the list but haven't heard from him in a while.. @seahorse@midwest.social u good? We dont have to worry about tesseract, right?

seahorse@midwest.social · 4 pts · 25d (1 reply)

Hi, I didn't know what this was til now

Pandantic@midwest.social · 3 pts · 25d

cool, cool. I thought we were good but it doesn't hurt to check.

Mucki@feddit.org · 3 pts · 25d (2 replies)

I do not understand why everyone is using the name of the codebase "tesseract" - which is in conflict with the absolutely wonderful concept of a tesseract - that is a four dimensional hyper cube. Why shame this beautiful word instead of shaming the name of the developer behind the fuckup? Save the word tesseract and shame the dev behind the frontend instead. Anybody care to explain their frivolity?

emergencyfood@sh.itjust.works · 2 pts · 24d (1 reply)

This drama started off as a PSA to users and instances using Tesseract as their default Lemmy frontend. The dev has at least two lemmy accounts and a different username on github; the software is better known than any of their names.

I see, thanks for the input. So then fuck Admiral Patrick and his other pseudonyms!
