I have data... 7d from a single platform with about 30 forums on this instance.
4.8M hits from Claude 390k from Amazon 261k from Data For SEO 148k from Chat GPT
That Claude one! Wowser.
Bots that match this (which is also the list I block on some other forums that are fully private by default):

I am moving to just blocking them all, it's ridiculous.
Everything on this list got itself there by being abusive (either ignoring robots.txt, or not backing off when latency increased).
