Wait, why should the default public position be “This is unacceptable and unwelcome here.”? As long as (i) this site is accessed in privacy, without bothering other people's sensibilities and (ii) the models are willing and well-paid (which, as the article itself states, seems to be the case), what is the problem? It's clearly one dumb-witted idea, but that doesn't make it automatically unacceptable.
If, in a porn movie, you have a guy who came in to fix her computer rather than the mythical pizza guy showing up, should SV be ashamed, because, you know, it's related to tech?
