If you haven’t already noticed the drop in your total number of subscribers on YouTube, then you might have not been affected because of the routine maintenance by the video-sharing platform.
According to YouTube, they have reduced the number of subscribers to combat spam and closed accounts.
The closed accounts on the site were either closed by the user or removed by YouTube or Google for violating their terms and conditions.
“If we removed closed accounts from your channel’s subscriber count, you’ll see this reflected in YouTube Analytics for Dec 3 to Dec 4 within the next 48 hours. From YouTube Studio > YouTube Analytics > select “See more” under the graph > Subscription source > Closed accounts. Since these accounts are closed, removing them from your subscriber count shouldn’t have an impact on watch time."
Heads up: Some creators will see a decrease in Subscriber count today as we remove closed accounts.— TeamYouTube (@TeamYouTube) December 3, 2019

YouTube says that the drop in total subscriber count is no big deal because those closed or spam accounts were not viewing your videos anyway. But the total number of subscribers do play an important role for many reasons. While they can simply attract more subscribers and people to your channel, they can also give access to several YouTube tools and features like Super Chat and YouTube Stories, which require 1,000 and 10,000 subscribers respectively.
YouTube has further mentioned to a source that channels would lose 15 subscribers on average. This wouldn’t sound huge to some but would matter those for whom every subscriber counts!
