Sandman made this claim in his Tom Brady video which I don't want to post here, where he claimed in the last part of it that Youtube was restricting his videos and stopping new people from seeing them.

It's certaintly true that his videos are getting less views in the last few months, but other Red Pill videos are still getting lots of views. Is it really because people have just gotten sick of him? Did he ever consider that? The fact that he was complaining that older subscribers were losing interest in him and new people weren't replacing them was funny and says everything you need to know. I thought Sandman was indirectly admitting that he's just become a lot less interesting and isn't able to rope people into his little Internet cult as much as he used to.

Another thing he was complaining about was that alternative videos websites, like Odessy and Rumble, don't get anywhere near the amount of views that Youtube has and they are full of the really batshit conspiracy theorists, who've been driven off most other social media. Youtube is the only real place for him as his viewership is dropping. He complains about getting less donation money as well.

Basically there's no evidence of Youtube restrictions and other Red Pill videos are still gettings loads of views, so I think he's full of it.
