yeah, fediverse platforms not only have no measures against scraping, they willingly send out content in a computer-readable way. kind of the whole point of federation. and we can’t really stop them, even if we clamp down on federation we’d only hurt ourselves.
besides, up until the latest change twitter was still easy to scrape (and now the problem is that even registered users can’t see that much of it), and reddit is trivial to scrape even without the api. yes, that includes new reddit too. there’s very little you can do against scraping in an open space, especially against someone wielding the full power of chatgpt, and even less so if you want to keep your site accessible to blind people.
