The article contradicts the heck out of itself.
Says billboard estimates she earns roughly $4k a day from Spotify streams. Then they speculate she makes roughly 8k a month from OnlyFans.
That would be like $120k a month from Spotify and $8k a month from OnlyFans.
That is FAR from more money from OnlyFans. Even if those numbers are hugely off I don't see how the discrepancy would be THAT large.
