Artists deserve money. Artists deserve to be paid for all the hard work they do. However, I believe it's a bit of an afront to the culture of this website to post paywalled content. Plus I paid for the content, and it's not worth it, especially since there's no big folder with all the different parts of the works for this artist. You have to view it in separate posts.
Edit: My fear is that it will become the norm, where people treat this as an alternative to Twitter and just post incomplete or censored "previews" to content like a pornhub model with a clips4sale.
