Apparently, you can  be registered on other countries if you wish to do so. In most cases, some platform tend to do it to evade being locally registered and taxed on their own country. Whilst some do those due to the fact that their country has strict restrictions with implementing online platforms and integrating their businesses onto it. Thus, it can conclude that they just registered their domain in RU, yet still tells users that their main business is located in China.

Overall, I never disagree to the fact that their platform is indeed unpleasing to any user. Yet what ever the reason is, it is better to keep this thread as a warning and not a proven accusation. Why? It is a huge conflict once you accused a probable legitimate business. Nonetheless, I still support your judgement yet everything only lies on just pure warning to other potential customers of their platform. Goodjob!
