I remember having doubts about this guy because he had reached such a level, yet had only one TK vid on his youtube. To me, it didn't make sense: he should have like zero tk vids or more than one after all the training he must have done. But now that I can see the rest and know that he stopped, it makes sense, I must have discovered him before he vanished from the scene.
As to why it stopped, when I had found his channel, there was one tk vid, and the rest was stuff about conspiracy: maybe he became a bit paranoid after reaching a level that makes it more difficult to go on unnoticed except by fellow psychics...
