[Ed. – How does this differ from porn?]
OnlyFans is a social media platform, not unlike Instagram, Twitter or Facebook. However, this website has a catch: Users must pay a subscription fee in order to view the profiles they want to follow on the site. OnlyFans explicitly states this in their FAQ: “The media contained within your posts is fully hidden until the point of purchase, at which point the subscriber can view all of your content.”
Comparable to following a private account on Instagram (where the user must formally permit you to follow them), or requesting to become someone’s friend on Facebook (where the user must formally accept your request), not just anyone can see what a particular user posts.
But you’re probably wondering, “Why in the world would I pay money simply to follow someone on a social media website?” Well, the main reason is that OnlyFans exists as one of the few sites that actually allows explicit content.
