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!
This is how its going to end up being. Pewdiepie will lose a lot of subs, while T-series may lose only a little bit. This will put them ahead of Pewdiepie.
