"The internet is for porn" is the unofficial anthem of the web and it's true when you look at the facts: 25% of all search engine queries are related to porn. 12% of all online content is adult content. But that doesn't mean social media is for porn. Just post a NSFW pic on Facebook and you will be locked out of your account for days. Instagram is well known for its approach to pictures of nipples, and Twitter, while pretty sex-positive in its rules and policies, started to shadowban users with NSFW content. Tumblr, usually a porn heaven, just doesn't take off as a site that connects people.
