The Grayzone is banned from Wikipedia because "there is consensus that The Grayzone publishes false or fabricated information." (https://en.wikipedia.org/wiki/Wikipedia:Reliable_sources/Per...).
And pursuing the first link, I could also spot a couple of sloppy mistakes (text description showing a sloppy misreading of their document screenshot).
So is he more credible than that website you posted earlier? Probably, but only because that website is such a garbage fire. Does that mean he is actually credible? Not so much.
I'm curious what your assessment of bellingcat as a source is? Surely it cannot stand up to your scrutiny.
