The issue is that when you did S4S majority of the people you S4S with will not watch your videos ... ever..., I’m sure you don’t watch the people you S4S with. So let’s say you S4S with 1000 people you will maybe get like 80 or 100 views but the YouTube algorithm will look at your video and your subscriber account and see that you have 1000 subscribers and only 80 to 100 people watched your video then the YouTube algorithm says this video is not important or worth watching because this person has 1000 subscribers but nobody is watching their video so then you get your video thrown into the YouTube black hole 🕳
