YouTube is taking away likes and subscribers now

Obviously I am not the only one on YouTube who has been shadow banned for a whole year. There are many videos about it, and other creators who have experienced the same thing. So recently when I’ve been uploading shorts, I will get a decent amount of likes, but then 5 minutes later the likes on that short drastically decreases. Ex: from 58 likes down to 39 likes within an extremely short time period. It’s extremely frustrating and I get the feeling that the algorithm is purposely doing it… but WHY? What good does that do? Same issue with subscribers. A short I uploaded does decent and I gain 2 subscribers from it; minutes later I loose 4 subscribers. Super odd. Any advice???
