Interesting, it seems there's a way to handle it within the Russian
Federation without going through a UDRP *1: by addressing the Moscow
Arbitration Court which is accustomed to those disputes.
If previous ownership can be shown plus TNF supports the action, I
guess it could be worth a try indeed. But 10k rub isn't that a big
amount and the time spend to organize all this will eventually exceed
that. However I am interested, do you think there's a simple way to
file a complain to that court without hiring a layer?
