I get where you coming but we actually do need "regular porn" back on this website.
The framing here is of a binary between industrial, transgressive, nudity-free erotica and profit-oriented studio pornography; when most of the porn being made today sits entirely between those two axes. Sex workers who are making the shit studios would never do, the ones who are doing it for rent, and yeah even ones who are making lame boring shit. That's "regular porn". Those are the people who fucking lost to tumblr porn ban. Brazzers didn't lose a dime.
I think unless we are able to express our bodies without shame or censorship, you're not actually challenging anything. Videos of machine eating paint cans isn't transgressive, it's allowed. Tumblr and it's shareholders are perfectly happy for you to get off to goop because that's not what stops their advertisers from pulling out.
I don't think adding "we need regular porn" to posts is funny. it's annoying and uncreative. But more importantly I think it's completely wrong in the idea that the bizarre and sensual only develops in (or as a consequence of) an absence of other outlets. In fact I'd argue its worse. We were almost on the cusp of recognising that pornography isn't defined by big studios, I remember it! and then tumblr annihilated anything but them from their ecosystem. And look at the culture here since then, its dry, puritanical, and utterly hostile. We've been set back almost 10 years of gross, esoteric weird fucking porn. Or at the very least, it wasn't and isn't happening here.
You're can't challenge the notion of pornography without sex workers. We need regular porn back.
