Debian and Fedora have ports, though not all packages are available, and you'll probably be doing a lot of porting if you want anything else.
But this bit from the uConsole R-01 product page might be relevant to you:
uConsole R-01 is a highly experimental model and requires some experience with Linux systems & FOSS. We strongly recommend all beginners choose other models.
A lot of this stems from instances running old versions with loose registration requirements, like no captcha. This is a problem in a federated system because there's no barrier for a banned user to just jump to another instance.
Perhaps it would be a good idea if, when Lemmy has anti-spam measures implemented like rate-limiting and captchas for registration, it disabled federation with instances that are at a lower version, to motivate small instances to upgrade and enable the new features.
Yes. And that doesn't excuse it; a moderator should be better than the community they moderate.
