Hey @YouTube why did you just emptied my sub list with no warning, i was subscribed to hundreds of content creator and now it's just 5 of them.
Great job :)
YouTube doesn't automatically unsubscribe creators from users' channels. It could be possible that your account may be logged in multiple devices. If yes, signing out from all devices and signing back in may prevent this from happening again: https://goo.gl/84MFdo
