As for new artists that get recommended, a quick search should be able to make it clear if an artist is a real person / group no? With tour dates or pictures and stuff?
There are many artists who are human but do not post their pictures and do not do live gigs.
Read their blogposts, including the older ones, before you judge. The person has recieved a loooot of harrasement behind the scenes, so I would ask you to not say mean things that contribute to it. The station is still live and has a great directory available of hand curated fediverse artists. The ethos of ethical music discovery will be continued, one way or another, by the community, even after the station closes down.
