Either i am crazy or @YouTube just subscribed me to many of the channels i previously unsubscribed. I noticed because i unsubscribed to @Kwebbelkop yesterday and when i logged in today, i am resubscribed and receiving videos in subscription.
We recently combined YouTube and YouTube Gaming subscriptions, so any channel you’ve subscribed to in one app will now appear in the other app. Here’s more info on the update: https://goo.gl/zfgfC4
