Chinese originated spam and abuse is so outrageously widespread, I don’t understand why there isn’t a conversation going on about cutting them off from the wider internet. They blocked most of it anyway.
It's not even a new trend either. Back in 2003 when I worked at eBay and PayPal doing security, the bulk of the attempts came from China and Romania (Romania at the time had one ISP for the whole country that was fast but didn't care about abuse at all).
