That website will have an IP address and a registered owner. Taking down piracy websites is routine for governments, server providers, and domain registrars now, and they don't care whether the site is actually illegal. You can only get away with this long-term if the site is hosted in Russia, but Russia is sanctioned so how will you pay them?

Eh, somehow The Pirate Bay, Fitgirl Repacks, Anna's Archive, Sci-Hub etc seem to manage it.

The real challenge is delivering good enough performance that your site is better than waiting through 30 seconds of ads; and making it worth your time to run the site: there's hassle, legal risk, and it's not like you can run ads to make some cash.
