Agreed. But I don't think it's 90% bullshit. Looking at that account months back they got several things right and the drone footage is useful.
They also posted what they called "british army papers" detailing assessment of ukrainian troops training on the uk and the assessment concluded that the ukrainians had the IQ of donkeys.
They also happened to be poorly made fakes because you know, "british army papers" don't tend to cite american laws and regulations and use american lingo in their legal boilerplate at the top and bottom of the pages.
Just because these channels report things western media doesn't report, doesn't make it true. You know, like rybar reporting that between the 5 and 10 of october russia would nuke an ukrainian base or that greenhouse lights reflecting off clouds are secret nuclear lasers.
You need to follow basic info hygiene: follow both ukrainian and russian telegrams, compare and find the matches... but that's only useful for frontline news. And frontline news is the only thing these telegrams are good for.
