Yeah I had the same thing. All of a sudden the load on my server was super high and I thought there was a huge issue. So I looked at the logs and saw an AI crawler absolutely slamming my server. I blocked it, so it only got 403 responses but it kept on slamming. So I blocked the IPs it was coming from in iptables, that helped a lot. My little server got about 10000 times the normal traffic.

I sorta get they want to index stuff, but why absolutely slam my server to death? Fucking assholes.
