Why do I keep being recommended v tubers despite my best efforts?

Every time one appears on my youtube, twitter, or other misc networks I hit the "not interested in this content" and the "block" buttons. I don't want to see it. I have being doing this religiously for YEARS. Why are they still being pushed to me? If big data is harvesting the virtual equivalent of my organs, the LEAST they could do is get that shit correct. I can't go anywhere without seeing one.
My initial thoughts were "well they're just becoming more mainstream" but then again so many other things are mainstream that I have actively blocked and "not interested"ed, and I don't see them? Why is it only v tubers? Does god hate me? Thanks.
