The wild part is, at least on tiktok, downvoting or selecting "not interested" seems to give me MORE of that content. It's as if leaving the video on your screen for longer is giving that video more points in the algo than your expressed disinterest. What works better (on tiktok) is to scroll away with the minimum amount of time spent looking at the video.

Makes me appreciate when there's a big message in the first second that says "wait until the end!" I swipe so fast when I see that. Otherwise I might have to wait to hear what they're doing in this video, which would boost them in the algorithm.
