So what does it actually do?
People's expectations when reaching 250 subs or unlocking ink support: Finally I get to make money from my series! It has been thriving like nothing before! I'm gonna make cash and clout, I'm so excited to make the next episode. My subscribers will be happy for me! I'm gonna make celebratory thread on forum.
Reality: It takes you some time to reach 25 dollars (minimum amount to withdraw, after fee), especially if there's no event like inksgiving. The 250 subscribers and growing more like I'm gaining more dead subscriber, oh look someone unsubscribe! Not all of them gonna give you ink. The celebratory thread on forum become a self promo thread and nobody cares about your series when they can promote theirs.
