I haven't been on twitter in months, and now you can't browse the site without logging in. My advice Read the bios. Is it from someone from a real org, or is it just someone with #OSINT in their bio and patreon.
Off the top of my head is HI Sutton. He's good for submarines. Rob Lee RALee85 is pretty good as well. Then there's the Jeffrey Lewis (ArmsControlWonk). Pay attention who those people follow. They do this for a living, and have been for decades.
Thanks for the vote of confidence in H I Sutton, I've recently been recommended his videos and wasn't quite sure how seriously to take them, even if they do appear well researched on the surface.
Anything that comes out of Bellingcat or those associated with it has been good in my experience, although that's from a layman's point of view. Their now-defunct podcast went into a lot of depth and talked about their methods and it all seems very good.
