Who the fuck has a good idea for secure communications between like minded individuals? I am trying to figure out a secure and anonymous way of communicating using old fashioned physical mail. I can't figure out anyway to prevent it from being centralized.
you're years late to the game and you should never speak outside your trust network and only in person. But here's the real thing, you don't need to coordinate anything, do you think Antifa is all top-down and coordinated through secret networks? No. They get their targets through public media and open sources and self-organize from there. Sure (((NGOs))) assist, but they don't need to give many specific orders because Antifa already knows what to do.
The whole terrorist cell thing is a compartmentalized with most members only knowing their direct collaborators, cells can't rat on each other because they don't know each other. Read up on COIN learn how real terrorists do it, learn how the government identifies and catches them. Here's a big hint, get rid of the cell phone.
