The person that started the thread didn't ask about working Russians. That is Russians operating from their own sovereign territory. He made note of the Russian prefix's that were operating illegally from Ukraine territory. Notice they do not even militarily control Luhansk or Donetsk, let alone Kherson Oblast. They don't even control the capital city of Kherson oblast. any more and haven't since September 2022. Let alone the genocidal murder of thousands of Ukrainian citizens.
You know that for evil to triumph all we have to do is nothing. So as far as working Russians in Russia that is one thing. They are not likely to be the cause of any of this, although the majority of Russians still support the invasion. But working an illegal occupier on Ukrainian territory, I DO have a problem with that. If you cannot look evil in the face and say no, then that is on you.
I suppose you all would have worked German stations in occupied France 80 years ago too? Would that have been a good thing? I don't think so.
