I watched a few videos on texting and suddenly I am getting recommended all these "in field' videos of approaching girls with like no views.

Are guys really doing this - can I do cold approach like this or is it all bs

I got recommended one and the guy says you are cool or something and the girl is immediately nice and starts walking with him. Does stuff like this work - or is it bs?

I don't know if the reaction's are real : https://youtu.be/K1zgZNgrtFc

Are their in field videos that are real? What methods actually work in daygame
