Though: how even to deter the "AI" scrapers from scraping that mirror internet, without excluding old devices
All the solutions seem to be either:
Basic things that scraper devs don't currently consider because they're lazy / don't care / etc., but could easily implement if they wanted to
Proof-of-work (which, even if we somehow could get it to work without JavaScript — nothing says that the mirror internet has to use exactly the same protocols as the current one — would make entry to the website very slow on old devices...)
Was it "proof-of-work"? I might be using the wrong word
Basically, they make every visitor of the website do a lot of calculations, to make it expensive to scrape and also excluding anyone on an old device or a browser without JavaScript
