Bellingcat's founder basically started OSINT journalism, and most "citizen journalist" documenting protests in France use techniques he shared (Yellow jacket mouvement included).

Bellingcat itself share techniques and tools it use openly. You can think they choose what to report on, but when they do it is liekly to be true, and you always can check yourself.

What i really like is that they give the tools to "do your own research" quite often, and that make them harder to deny.
