If not, it may be worth a try. They seem to do a lot to steer Youtube's recommender away from the more gamy regions of its latent space; for example, something like a year ago I saw recommended such a video, immediately reported it for "violent or repulsive content", and thus far haven't seen another. The same has been true for the occasional weirdo along the stripe of modern Russell Brand.
To be clear, I don't think the report was acted upon by Youtube, but I do think the signal inherent in the action must be accounted for in its recommendation model.
Also to be clear, this is no defense of Youtube. It's pretty trash these days, and even the most innocuous recommendations I get have very little to do with anything I'm actually interested in, but this does seem to keep it from getting the idea I might want to see incels and gore.
