As someone on the fighting end of scrapers, this is absolutely not true. If anything I should bais towards v6 as the traffic is on par better than v4

Just remove the A record, and nearly all the scrapers disappear. :-) (And then you get one email per month or so that “your host does not resolve in DNS”.)

Google is having a real issue with LLMs using it for search. As in, real load issues. Unless you're running a publicly accessible search engine, and the top one at that, the LLM traffic you're seeing is not representative.
