Seeking Clarification: Why Are Music Promotion Posts for New Artists Considered Spam?

As an enthusiastic supporter of new and upcoming artists, I've been sharing posts about them on this platform with the intention of promoting their music and talent.

However, I've noticed that some of my posts are flagged as spam or removed. I genuinely believe in the potential of the artist and want to help them gain exposure. So, I'm left wondering why these posts are considered spam.
