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!
I'm hoping this means going through accounts and verifying they're spam from suspicious activity instead of just cutting off subs that don't click on videos for a while. That would REALLY fuck with everyone
