Hello
I am happy on this instance and 2 other federated instances that take good care of the culture by not federating with some other instances.
Yet sometimes I wonder what the “firehose of trash” would be like if I would see really everything and am wondering if there is a “catch all” Instance that is not limiting anything at all?
I would like to take a peek down the abyss for once.
Those are test servers for Lemmy.ml (for new versions, I think), by the Lemmy devs. I don’t think they’re banned for ideological reasons, and you won’t miss out on much by blocking them.
