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.
To all the users who made the blocklist, your Lemmy experience has been greatly degraded by not interacting with the users of tesseract. The fediverse may never again know their like. They few, they few, they happy few You will think yourself accursed for not being there. You will hold your manhood's cheap whiles any speaks of tesseract and the ban list of this day.
