Wallworld was a graphic novel, set in the deep future. It depicted daily life in a small society of survivors of an atomic war. It was irregularly published on internet between 2010-2013, when it was suddenly deleted. The novel had no real name, but it was called Wallworld among the few fans.
It was purchased by an American law firm in 2013, who took it off the internet. It had less than 300 followers, but they were all contacted and threatened with severe copyright infringement charges by the law firm if they had taken any copies of the pictures.
The same law firm also tracked down the few original artworks that had been given away, and bought them all, paying up to $342000. This remained a mystery for two years.
The truth was revealed in 2015. John Gladstone, an American Investor, had been investigated for charges of market manipulation and insider trading. An anonymous portfolio had been traced back to him through various holding companies. This portfolio had invested on 78 occasions between 2012 - 2013, with a holding time average of 3 days, with an average profit of 83% on each investment, with only one that ended up red.
The Investor himself claimed that he had gotten these tips from the Instagram story Inside The Wall. It was his law firm that had acquired everything there was to find about the story. The case was closed through a settlement fine when the IRS found four unrelated Americans, none of them investors, who had made several of the same investments, telling the same story.
The owner of the Instagram account was not the author or artist of the series. The author himself could never be extradited to USA for hearing. He was incarcerated by law in a Swedish mental institution, and considered too dangerous to transport. His true name was never even revealed by Swedish authorities.
This story never really got any media attention. There was never any evidence against the series itself, the five were believed to know each other from the series comments field. There was an obvious connection between these five, and a settlement was reached before the series or comments fields were even used as evidence. The entirety of the series was submitted as evidence for the defendant, so it was never destroyed. It has to my knowledge not been published since, and with 300 readers ever of an 800 page illustrated story should make it one of the rarest reads ever.
The only review it ever got said "It's as boring as Days Of Our Lives, but incomprehensible. Everything is weird, nothing gets explained, and I don't get the inside jokes. And they're all so ugly!"
