I realized, from the comment section and email, that I may not have been entirely clear in my post, which made it sound like I don’t believe that it could have been a coding error of sorts. I think the base event that caused this to happen could have been a non-native English speaker trying to inject tags he assumed were code for “porn”. And that’s exactly what people mean when they say that there’s systemic oppression. Gay people and feminists seem more porn-like, because independent women and gays are sexualized to a degree that straight men are, so of course certain words remind people of sex more. More even than blatant pornography, which has been mainstreamed to such a strong degree. Ron Jeremy’s a mainstream figure, for instance, and “Girls Gone Wild” is advertised on cable TV. Playboy magazine has had more mainstream TV shows that feminists could command. Marginalized drifts to “illicit” in people’s minds, and so an honest mistake could also be the product of systemic oppression.
And that’s what I mean about how adult classifications drift towards oppressing the expression of gay people and feminists, unless you put a great deal of oversight into the system. I suggest that eliminating the “adult” classification is the better way to handle this, especially since real porn isn’t going to get dinged by it, since it’s so mainstream now.
