Of course, there are. Parasite sites work and will exist as long as SEO does. Everything exists; it just changes in how it works.
Since I am focused on automation, almost all of my sites are automated in terms of link building, and 80% of the content generation is automated (now, I am looking for a good solution, and you can read about my journey in the blog I am writing).
Ten years ago, I used GSA with junk content which I bulk-produced using Kontent Machine and spun with Spin Rewriter. We could even use Google PR... I remember tools and free trials on Ahrefs, lol.
But now, things have changed. We use GSA with GPT-4 content and generate content with AI. We filter out for Ahrefs, Majestic, and some pinch of Moz metrics instead of Google PR.
