Which videos/topics are affected by that, in your opinion? Just curious what you have seen, since they have videos from multiple countries by multiple authors.
My memory recalls an interview from a guy who escaped from Korea. There were other warning signs as well but much more subtle and I don't recall them exactly. Like some people are being a bit too positive or some people seem to be oddly specific in their answers.
I'm sure they have legit videos as well, but I can't be bothered by such channels.
