Do we have any numbers on how many subs does the channel have and how much is the viewer limit? I have a small YT channel for local OSM chapter with 15k views & 300 subs, good to know they could fuck me over if I ever try to make a live stream that would blow up... Not that I ever had more than two dozen viewers, but social media engagement has proven to me to be very unpredictable in both upside and downside.
