- Most popular social media websites allow adult content in some forms.
- It is no easier to tell illicit content from legal content on one site versus another.
- There is likely not just far more content, but far more adult content on Twitter and Facebook than dedicated porn websites.
- Sites like Twitter and Facebook better facilitate private conversation (presumably.)
I don’t think you can make money on Pornhub without verification, so there’s probably not a money incentive to intentionally post illicit content. In fact I’m not entirely sure why you would at all, but my best guess is in hopes of trading with others. In that case, social media is actually perfect: draw people in with carefully constructed fronts, do dealings in private groups and try to fly as much under the radar as possible.
It’s hard to say and probably silly to speculate but I just don’t see the point of using a pornography website for this.
