It's the provider I'm using that does it for the Tor exits people host with them. I don't have my own IPv4 space, which is something like 8k$ for the smallest useful subnet and that's too expensive for a hobby.
They just have a Russian ASN and IP space but it's still located in Norway.
you have a german nick name suggesting you are german, you run tor nodes in norway which appear to be located in russia ... i think that is already a lot of technically interesting stuff. also many people would probably like to understand why you do it and how much you spend for this hobby(?).
If I was Russian, sure. I think it’s best to always use exit nodes/proxies in geopolitically opposed countries to prevent collaboration between states. E.g. use western VPNs while in China, use Russian/Chinese tunnels in the west.
In parallel with gea0's comment, using a Russian state-sanctioned exit node would make tracing efforts difficult-to-impossible for western government / law enforcement.
