Barbara Marciniak published several books channeled by Pleiadians and is respected as genuine source. I like her books, but find them a little too high level. They speak about many things far from Earth but little about specific material problems here. Still, the books were helpful for me.
Barbara Marciniak is not well present on YouTube. There are few audio recordings posted by other people.
