FYI a significant chunk of Chinese IP space has been banned (self.main)

Good morning everyone. Just a quick heads up that I've banned a good chunk of IP space in China due to abusive traffic.

I've tried to restrict this where possible to datacenter blocks from Huawei, Tencent, and Alibaba, but China Telecom / Mobile were also heavy sources of suspicious traffic. I doubt we have many (if any) users in China, but if you are affected please let me know.

This has been ongoing for a while and I ignored it initially since the traffic levels were low, but it wasn't anymore.

The ban has very visibly cut our traffic levels:

Haven't done ops in a while, is there any good automated system that can block IPs on individual basis based on activity patterns? E.g. trying to login with the wrong SSH password too many times, but relevant to our use case?

Fighting with bots is pretty hard. LWN has an article sharing their methods https://lwn.net/Articles/1008897/
