Saw it on reddit. One of the rare TILs that I hadn’t seen posted a dozen times, and it’s actually fascinating.
Nauru is also famous as an easy mill to get your commemorative stamp or coin issued.
Back in the bad old days of the internet, when you couldn't get a .com address you could always get a .nu, .nr or .cx. They were generally an indicator of low-rent, trashy content in an era before myspace. I always thought .nu was Nauru but that was .nr; .nu is Niue and apparently Niue is gorgeous.
