It's going to get to the point where everything will be put behind a login to prevent LLM scrapers scanning a site. Annoying but the only option I can think of. If they use an account for scraping you just ban the account.
logins are more easily banned, and highly complex captchas for signup needs a human to signup and solve. As long as it's easier to get banned than it is to signup it will at least deter.
