Are you aware that your youtube presence is under systemic attack by "fog-bots"? I have noticed this activity against the youtube presence of all major progressive speakers - it is clearly a well organised and funded tactic used to contain and limit the narratives of important progressive players. It works by flooding the youtube search with random posts of your work excluding your latest contributions: thus obscuring your overall narrative and most cogent contributions. I would suggest you look at installing a counter-bot to neutralize this attack and keep your current contributions at the top of the search list.
Thank you for your suggestion, Mitch, we will look into this issue for Prof. Wolff's channel.
