PornHub's audio description sucks balls. As a blind listener of porn, I'd rather hear non-described porn than they're obviously BS to advertise. When I listen to porn, I want to know what the dialogue is, if any--there are a lot of pornos with dialogue. The narrator, in an attempt to describe every little detail, most of which I could care less about, actualy ducks the audio so she can come in and describe everything--you have her, sacrifice the audio for this horribly produced effort.
Second, you know that money was the only objective when they haven't updated the videos. They wanted to reach out to us? Complete and total bullshit. There was a porn studio back in 2007 or so called SOundsDirty. They're audio description was head and shoulders above this crap and sounded like a commercial effort, like your average audio described television show, but porn, with high quality 320KH audio.
I'll have to check out this GoneWildAudio sub.

So I just checked out GWA. Needless to say, I could get better professional quality audio out of an Erotica book purchased on Audible.
The "About" section implies that people are actually posting recordings of themselves going at it. Nope, it's pretty much an Amature Erotica actors guild. People write scripts, somebody requests scripts, etc, they're written, and somebody else from the sub records a rather sub-par recording reading the lines.
I think I've scene posts of recordings that imply something more, but of course all of these have been removed. They even have their own site for audio, soundgasm.net.

Apparently /r/gonewildaudio is a thing, though I've never bothered with it.

Edit: Yup, just clicked it. Wish I hadn't. But, well, it does exist. Also this:
