Activated the purchased key through another region.

Greetings. I live in Latvia. I bought a key for a stimby, but I managed to activate it only after changing the IP to the Russian one. I can't understand right now. Some write that you will have to start only from the ip rashka, and if you log in from your own, they will be banned. Others, that only the activation process is important, but from where you play is no longer important. Does anyone know for sure?
