I just blocked the entire 47.79.0.0/16 subnet from my server because it was querying hundreds of nonsensical pages from my web server using a bogus user agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/140.0.0.0 Safari/537.36.
Each subsequent request was sent from a different IP address in that range to evade rate limiting. I've learned this IP block is owned by Alibaba Cloud LLC, good riddance.
