Sopuli is Finnish, some Euro community are on there, although there are many generic communities as well.

Even from a major instance (one of the ones that was successfully federated by a bot)?

Try searching for the community via your other Lemmy accounts. Might be first worth posting something with your mod account first.

The tool enables first time federation for new communities.

Try adding the community via this tool:

I would actually say OP should remove the [satire] tag. Good satire is when it’s difficult to figure out whether you are making fun of the topic or agreeing with it.

Adding a [satire] kills the whole comedy vibe.
