What I do is clear watch history if I accidentally watch something on the website itself, but on the account where I actually want good recs I haven't updated my watch history for 7 years now. It just cuts off at a point and anything new I watch gets marked "not interested" (which does seem to work for me, I think continuing to watch and have updated watch history contributes to them reappearing, but for anyone else you can also report them for violence and such to make sure they stay hidden).
