I remember that, back in 2013 or 2014, PUAs used to control the market of selling their ridiculous guides of "how to pick up woman" and redpill started, taking too much "students" from PUA. I remember PUA used shaming and did not refute redpill fundamentals (which are ridiculous) and, after seeing that this strategy was not working, they started to incorporate redpill elements and present themselves as "redpill coaching".

I notice that PUA died now. It simply doesn't exist anymore. But redpill does have a lot of elements that came from PUA.
