Editor's Note: As Anza stated in the comments, TotalBiscuit is not shutdown, he just had a strike against his account.
Sega is filing copyright claims over users who have videos of 14-year-old Sega Saturn games such as Shining Force 3, Shining and the Holy Ark, and Shining Wisdom. The email from Sega that’s being used for this comes from a Japanese Sega account, many small YouTube channels have been shut down with 3 or more strikes on their record including the rather famous YouTuber TotalBiscuit.
No reason has been given from Sega and all the counter claims against these attacks have been denied by YouTube. Almost all of these videos that have been taken down were Lets Play videos and none were derogatory against Sega in any way, shape, or form.
