"The Machine Fired Me" would not get me to block the channel but I've blocked hundreds of channels.
I also block any channel that appears to be a rando repeating the latest hot topic.
Also I tend to do the "Don't recommend -> I don't like this video" for those that have the thumbnails with "that face" (you know, the YouTube Thumbnail Clickbait Face, I don't even know if there's an actual term for it).
When I actually enter a video, you have my attention by default and you'll get an instant dislike for:
- "Don't forget to like and subscribe."
- Showing those like and/or subscribe buttons on screen.
- If I get suspicious that you're padding video length, talking just for the sake of stalling.
