Valid points. Not trusting pornhub after it taking so long to clean up it's content might be the better choice overall. Especially if ethics in porn is a top priority. I do think consuming too much porn is a problem for some people and it could start to warp perception if the consumer can't separate reality and fantasy.
I think most people don't care about ethics in porn, so I try to rep any small push toward good. It's not perfect but "don't let perfect be the enemy of good" and all.
