Because, despite denials, Nabil appears to have created the site Marvel TV News which runs stories about Marvelk animation and games, but mostly about how awful the Ultimate Spider-Man cartoon is, and how everyone hates it. It is registered to a “Nabil Mjati” in Morocco. So, you know. That’s him.
And then he posted the news that the Avengers Earth’s Mightiest Heroes would be cancelled and replaces with the cartoon Avengers Assemble. He also quioted from a press release, purported to be “print only”, saying “The Avengers: Earth’s Mightiest Heroes won’t be renewed for the 3rd Season. Marvel Animation will present their newly developed series Marvel’s Avengers Assemble in 2013.”
Which was picked up verbatim by sites all across the internet, some like Comic Book Movie, Oh No They Didn’t, CBR,Critiques For Geeks, giving credit to Marvel TV News, others like iFanboy, ScreenRant, Geek Tyrant, Super Hero Hype, Comic Vine
Only problem was that the quote was made up. There was no official press release. It was a lie that few chose to question.
