Oh, I was more thinking in the context of a centralized service, although technically it should be possible to do this in a federated manner too. I don’t think the resources would be an issue, but the liability of holding this data would be. I don’t know how that works on sites that currently do this though.

You don’t need a blockchain.

Solvable by requiring verification of every user by government ID?

This group sounds great. Unfortunately, I don’t read Finnish. Is there an equivalent group in English anywhere on Lemmy?

Ah, yes, that makes sense now! If it is an automatic, random server selection, then I also agree that it should be only generic, non-controversial instances that are selected.

As long as it’s clearly labeled as something like “a communist instance”, why not? Some potential Lemmy users would probably feel right at home there. It doesn’t even have to be a controversial label, just a factual description that the Lemmygrad people would agree with.

create some set of rules for “default instances” - every instance that wants to be in the list must follow them and will be periodically checked

I don’t have any particular rules in mind, but some examples might include active moderation team, obviously registrations being open and if you really want to make it easy, either no application question or having it automatically approved by an automod of some kind

The Mastodon Server Covenant is pretty much what you describe here, and could be used as a starting point: https://joinmastodon.org/covenant

It’s so much easier to comment and get replies here.
