Deezer will tag it and refuse to promote it once it's tagged as such. You're not gonna stumble upon it by leaving the autoplay on and it will not appear on any of its editorial playlists. Quite frankly this problem would be completely gone if every streaming service implemented this same policy.

Deezer also does some other things right: they boost the artist payout if the listener intentionally searches for an artist/song/album instead of stumbles upon it via autoplay/playlists, they introduced lossless audio a decade before Spotify, and you don't even need an API key to interact with its metadata (of course you need to oblige by their rate limits).

Some criticism so that this doesn't look like a pure promotion: their apps are absolute crap in comparison to Spotify and Apple Music, and even in comparison with TIDAL, which itself isn't really a pinnacle of user experience. It's definitely the most frustrating one out of the bunch that I have direct experience with.
