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, it’s fine.

If you have vote brigading, ban them, take it up with the instance admin, and defederate, in that order.

Yeah but that’s a waste of light. Why use a floodlight when you can use a laser?
