@joenepraat @stux They have no jurisdiction, and there is no way they can enforce Russian law in the Netherlands. But they can try under Dutch civil law, with a claim of libel, like everyone else, and hire a Dutch lawyer from the Zuidas.
That would still not be a reason to give in, because it is unlikely they would win. It might cost a pretty penny if they decide to go all the way to the supreme court, so we best be ready to donate if needed.
