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!
Split on this... First of, kudos for YT actually being transparent and warning creators for once. Secondly, what's the chance that we'll end up getting un-subbed from channels we actually have been supporting for ages?
