I would appreciate less unsolicited opinion in the content guidelines, if I'm being honest.
So there are "plenty" of sites out there to upload uncensored comics with explicit content? Mind sharing some URLs? Because I know of exactly two, and one of those isn't even an actual comic host, it's just customizable for that purpose.
It's fine to have your guidelines, but this claim just attempts to reinforce to readers that it's fine, there are positively scads of them out there! That's not the case, and creators who incorporate adult-oriented material are most often treated very poorly and limited in opportunity. It's so bad that most of us have developed a way of life that requires us to be ready for being screwed over by whatever host we go with, regardless of their terms and agreements at the time.
I often wish there were plenty of sites out there for us to express ourselves creatively and artistically, without worry about censorship or someone clutching their pearls because of a sex scene. But this sort of language in an official site policy document misleads, which I don't think was the intention. I think it would be best removed, since it also adds nothing to the overall document, nor does it introduce a point of agreement.
