Though I'm not sure how useful a feed of raw information like this is without added analysis and contextualization

The value of OSINT is when trusted organizations like Bellingcat or Critical Threats Project do some checking, such as cross-referencing information from multiple sources and geolocating footage

Without that, whose to know the providence of the footage in these postings and whether or not they are some attempt at disinformation by a state actor?

But maybe NostrOSINT will demonstrate that they are a trusted information source
