Just got hit with a scam from a Chinese registrar company [1] telling me that my domain name in other countries (eg. domain.cn or domain.com.dn) is being taken over by a Chinese company.
After doing some research [2] this is a complete scam. Since CNNIC registry announced that the Chinese .CN domains were public, these sort of scams have increased significantly.
If you do see these kinds of scams, I would highly recommend reporting it to the FBI internet fraud team here: https://www.fbi.gov/scams-and-safety/common-fraud-schemes/internet-fraud
