Heads up, Creators: On Dec 13-14 you may see a noticeable decrease in your sub count as we remove spam subscriptions. If spam is removed, you'll see a YouTube Studio alert: https://goo.gl/qGDBvX This should help give you confidence that the subs you do have are real fans!
Just please don't unsubscribe me from my favourite creators. Whenever you've claimed to remove these spam subs I've found some of the channels I watch the most I've been unsubbed to. I would hate to think you consider me, a loyal YouTuber and supporter, a "spam account".
