In what I have seen personally, creating absurdly more load by hitting "expensive" pages that no normal user would ever click in that frequency. The AI scraper bots are really, really dumb - they just follow everything that looks like a link.
Another particularly annoying thing was when spam bots got brainy enough (if I were to guess with AI?) that managed to bypass our maths captcha. That one really still pisses me off because I don't like to torture users or having to use GDPR-violating services.
