This is not a "blacklist" in any reasonable sense. It's just a report the CPD issued which lists people who have been pushing pro-Russia narratives. It has no legal effect.

Their country is being ruthlessly attacked by Russia so of course they're concerned about foreigners who appear to be justifying the invasion.

All European countries censor, by the way, as there is no free speech there. That isn't good but doesn't make them Nazis.
