You're correct that there are more pro-Ukraine news/content at the moment and I'm also more exposed to pro-Ukraine sources than pro-Russia, although I try to follow both, and that might (at least partly) explain why I'm identifying more false news in the pro-Ukraine camp, but even with that explanation it doesn't change the fact that among all the news circulating about the conflict more pro-Ukraine news are turning out to be false.
And I'm not talking only about 'memes' which are effective propaganda tools promoted even by the mainstream media (let alone Facebook, Twitter and Youtube who pretend to fight misinformation
), I'm also talking about the news spread by the pro-Ukraine camp. Even today we had the news about the fighter jets coming to Ukraine, which also turned out to be false. I get it, it's part of the war and they're trying to raise the morale of their troops, so I don't blame them for it, just stating my observation.
