Nope - I'm not going to start subscribing to channels. Their algorithm has plenty to work with based on my watch history and my spam reports (I've reported every single one of these scams I've come across, usually directly from the recommendations page - not even clicking to watch the video itself).
I'm interested in such a wide range of topics that I prefer recommendations based on individual videos I've watched rather than specific creators/channels. I'm glad you don't get these in your feed, but based on others in this thread, it sounds like I'm not that unique in experiencing the issue.
