MostRomanticSite.com - I created a side project to build Internet's most romantic website to prove to my wife that I am romantic. :-)
They were fast:
BBQboy and Spanky (Frank&Lisette):
https://bbqboy.net/category/africa/
thevagabondstories (Harry&Nikita)
I have been part of digital outreach campaigns in my company where we bring many micro-influencers on board before the launch.
So, I think maybe he also would have asked few hundred people to join by mass mailing them.
