In an unexpected turn of events, the director of the Pirate Bay documentary TPB-AFK has sent takedown notices to YouTube requesting its removal. The director states that he sees the streaming portal as a radicalizing platform full of hate. The takedowns are not without controversy, however, as TPB-AFK was published under a Creative Commons license.
There’s nothing inherently illegal about the service or how it works which is why it isn’t outright banned. The illegal part is sharing copyrighted material over the service and I think you could get caught doing this just like someone using regular torrents without a VPN would be.
