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!
Does that mean you'll be purging subbots too? I know a bunch of channels that violate TOS like that through sites like promolta on the regular.
