We don't. I probably should make one of those, but as a solo act, the number of platforms I need to keep up with is ridiculous. Reddit/Spotify/Instagram keep my time occupied, it's brutal honestly.
As a solo act, I also agree. There's 24 hours in the day and to do the metadata correctly for the releases themselves _just to send to the distributor_ takes like 1-2 hours. Then I need to make content, when I just wanted to make music, then upload the same release to Bandcamp. It's untenable
