Im not sure if this is the right sub, so please point me in the right direction if I'm in the wrong place. I saw a post here on Poal (on the front page, I didn't look at the sub) a few days ago regarding a Soviet NKVD PsyOp designed to encourage dissenters to identify themselves by availing to controlled oppositional organizations throughout the USSR. In this way, dissenters who might otherwise be seen as patriots were unmasked and sent to gulags or killed. Does anyone know the name of this program, or have information about how these programs work and their effectiveness? I'm genuinely interested in this as a topic. Thanks for your time.
