Speaking as a perma-noob or just noob, I'm on plenty of other active forums.
Once YouTube stopped pushing flat earth content the interest died down a lot.
It has started slightly trending up starting around 2020, probably buoyed along with all the other conspiracy theories about the election and covid. I personally think Kyrie Irving is mostly responsible for the recent uptick. It will level out and drop back down once he's no longer of interest to the media.
