Have you tried preventing this in your proxy?

I mean something like this:
Ngnix:

if ($http_user_agent ~* (GPTBot|ChatGPT)) {
return 403;
}

Apache .htaccess
SetEnvIfNoCase User-Agent “GPTBot” bad_bot
SetEnvIfNoCase User-Agent “ChatGPT” bad_bot
Deny from env=bad_bot

You just have to find the other bots.

@bearleathermen Oh we've actually had GPTBot in robots.txt for ages, and they seem to respect it. The problem is the high-volume scrapers impersonating Chrome/Firefox/Edge/etc, usually just one or two request per IP.
