Aliyun asked me via email to send them ID copy, credit card copy, credit card statement for last 3 months in 24 hours otherwise my account would be shut down. I did so in 39 hours because I don't check that email account very often. All my running instances were shut down in 2 weeks without additional warnings. Only emails I got from them were about 20$ coupons for referral. As support later explained, I did not meet 24 hours deadline. (AWS haves me as customer last 4 years with 10's of thousands USD spent yearly and never asked for ID or credit card copies).
