Code for people interested https://codeberg.org/rimu/pyfedi/src/branch/main/app/admin/routes.py#L373
I commented it out, rebuild the Docker containers and it works now 👍
EDIT: People seem to misunderstand what it does. It prevents it from federating automatically when populating the community search, importing from another instance or from Lemmyverse. It’s not a full block, and you can still add it manually. Not only that, but it’s also already partially removed since I posted this.
Yeah… I’m unsure how they thought this was a platform-wide ban when it includes terms like “meme” and “greentext”. I don’t even need to look at any more than this one line of code to intuit this does something more specific than OP thought.
