Sasha,
The Mysterious Anuket explains it on her site:

She has a link back to YouTube, where she re-posted, and so far they have left it alone.
Apparently as it is their "corporate" site on YouTube, they can moderate comments.
If you look back into Anuket's site, she has been calling for accountability in PD research for many years.
