@TeamYouTube i would really love to know how you choose and what you choose as criteria to arbitrarily unsub people from channels they go to. I know this happened for a fact today due to one of My MODERATORS having to resub to my channel.
It's normal to see fluctuations in your sub count as we want to make sure the numbers are accurate, so we perform additional verification & spam reviews. That being said, could you check with your subs to see if they use any 3rd party extensions? Let us know.
