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!
So, where have you posted more information @TeamYouTube ? I'd like to know how your system knows the difference between a real account and a spam subscriptions?
