Lemmy by default will federate with all instances if you don't put instances in the "Allowed Instances" section. I've found, it's easier to federatte with all instances and ban the ones you don't want. Otherwise, you effectively use a whitelist to federate.
According to the documentation, the allowed instances field is to restrict federation to specific instances.
I'd recommend leaving it empty and leaving federation open
thank you! that's exactly what I was looking for. Was originally testing and added lemmy.world as an allowed instance and was wondering why federation wasn't working. TYSM!
Yup, I had the same question and was frustrated I was missing so many comments from instances that were federating. Just leave allowed blank and then block the bad ones unless your really concerned about bad instance actors.
