I've been thinking of maybe making and archives channel on YouTube reuploading most of everything on Adams old channel, but sounds like a lot of work.
Anyways, here's a video from his now removed YouTube channel, CulturalPhilistine, titled "My Antinatalism". Unfortunately every video uploaded to his channel features only a black screen, but you can still hear the audio clearly, which is something. Might upload more archives later, enjoy.
