Which is funny, because I noticed when I blocked a “right wing propaganda” channel the other day in the YT shorts section it just skipped the video and played another one from the same channel.
I’m pretty sure this is because YT loads what it wants you to see on Shorts in big blocks of them. So instead of loading a new one every time you scroll down, the next one should already be loaded. That means if you block one it won’t block the next one because the next one is already there.
