I doubt it. The scraper botnets aren't going to bother with niceties like APIs, they just come in over HTTPS and grab anything they can.

There was a whole mini-industry around scraping specifically Reddit using the API feed because it was so open. AI companies first trained on Pushshift, which is like Common Crawl for Reddit, which is why Reddit shut down Pushshift (with legal threats IIRC) at the same time.
