There exists an unofficial (MIT) channel of Lewin's past MIT lectures. It
is not associated currently with him and he does not comment or reply to
it.
The channel is called "For The Allure of Physics" https://www.youtube.com/channel/UCliSRiiRVQuDfgxI_QN_Fmw/about
Warn students about his past before referring them to this channel. But
they will not be at risk of being contacted by him in the comments.
Lewin's own channel which he comments with is different. It is "Lectures by
Walter Lewin. They will make you ♥ Physics" .
