I don’t hate him. I hate the omnipresence he has on some social media. I use YouTube a lot and I watched some of his videos before, but it’s not for me. I’m not interested. But YouTube keeps suggesting his videos to me. So I blocked his channel. But he also has a few other channels, or people reacting or condensing his videos, and even when I thought I blocked them all, some other new channel with his face eventually gets in my suggestions. It’s like playing whack-a-mole.
