This is an unlabeled advertisement for substack. Please stop the endless substack spamming. They just lie about the earnings they all have relationships with substack, stop fucking commuting fraud by allowing all these fake “I’m just a random influencer and I love substack” posts, it’s illegal to not disclose that they are paid to say this.
