My first filter is whether or not the piece of news suits obvious Kremlin goals. Like this "bellingcat" (that turned out to not be Bellingcat and the BBC report on the Bellingcat report was likewise a fucking fake) report on ukie weapons being used in the Hamas attack was obvious bullshit.
Russia and it's foreign allies have been crafting an entirely alternate reality together for 7-8 years now on social media and it's all bullshit, a lot of it obvious. The Fantasy Industrial Complex has carved out their causes and created an entire alternative worldview, anything that supports that worldview should be considered epic bullshit until independently verified.
