Basically, if you have a NZBN and sign up with HNRY, they'll give you 50c for free when you sign up to show the full breakdown of how it works ($1 to start, 10% to them, 40% to dummy "tax" and the rest to your bank account)
Definitely not worth the time if you don't have a NZBN to start with or in general really, but hey 50c is 50c.
What stops people just grabbing random NZBNs? They're public info.
