In my country (Italy) Visione TV had bank account frozen for putting on a webtv a Journalist that lived in DonBass during 2014-2018 period speking about local people killed by Ucranians.The decision came from Massimiliano Coccia, husband of Pina Picierno ( member of the European Parliament), this append also to Frédéric Baldan and a lot of other people every day, so I'dont wonder it its true.

Was it for what you say, or was it for transactions with sanctioned individuals in Russia that paid for the propaganda?

Visione TV is a mouthpiece of the Russian propaganda machine. The account being frozen was most likely the bank doing its due diligence due to the sanctions on Russia.
