I tried something like this years ago but never got further than: "HELLO WORLD." Nice to see someone "vinish" something like this.
It kind of reminds me of what Harry styles did to promote his album Fine Line. He created a fake country called Eroda that no one knewwas fake at the time, and sent out cryptic tweets without identifying they were from him.
I saw a few tweets and wondered if the "tweetist" had confused it with the actual country of Andorra which many people here in the states refuse to believe exists even when I tell them.
He even created a complete website for Eroda, promoting the "attractions" of the place, which exists to this day. Yeah it sparked interest in a lot of people before going viral and being connected to Harry Styles himself. Pretty creative idea, and I'm glad it all worked out for him.
It makes one wonder; where in the world would a friendly hypersensitivosaurus live? :)
