I'm guessing it's because they think that even with a custom domain, some deep headless-Chrome-scraper-based OF-link scanning (or just human flagging!) will catch on and get them blocked within a few weeks anyway. Which would make the $10/yr for a custom domain, more like $10 per time-you-get-caught.
It's the same reason that scammers/spammers rely on these services: the only hosting you can "acquire scalably" is free subdomain hosting.
(Now, why they don't use something like a Google Doc, that can't be blocked based on its URL and can't easily be text-extracted by a scraping bot? I have no idea.)
