This is pretty ingenious:

At the bottom of each Dispatch, you’ll see the option to unlock a sharable link. This link will be unique to you, and allows anyone to view the Dispatch without hitting the login screen. Links are valid for 48 hours each, and you can unlock a maximum of ten Dispatches per month.

Smart solution by allowing people to get a taste of the NSFWCrop greatness while preserving the subscriber-only access point.
