There's also the option of going into your Youtube history and deleting things from it. More than once I've clicked on something out of curiosity and regretted it, only to have youtube recommend more of the same, but removing the original videos that caused it from my history seemed to do the trick. My theory is that some video categories have a highly addictive nature to certain groups of people. Youtube's algorithm picks up on this, and notes that people who watch x are likely to want to watch y and z etc. It could be conspiracy videos, pickup artist things, young women, or something feeding off of an insecurity. The algorithm doesn't care, but it can pick up on these patterns of viewership and entices you with more.
