A Twitter user using the pseudonym of @TheHackerGiraffe has hacked over 50,000 printers to print out flyers telling people to subscribe to PewDiePie’s YouTube channel.

The messages have been sent out yesterday, November 29, and have caused quite the stirr among the users who received them, as they ended up on a bunch of places, from high-end multi-functional printers at large companies to small handheld receipt printers at gas stations and restaurants.

The only condition was that the printer was connected to the Internet, used old firmware, and had “printing” ports left exposed online.

The message the printers received was a simple one. It urged people to subscribe to PewDiePie’s YouTube channel in order for PewDiePie –a famous YouTuber from Sweden, real name Felix Kjellberg– to keep the crown of most subscribed to YouTube channel.

If this sounds …odd… it’s because over the past month, an Indian record label called T-Series has caught up and surpassed PewDiePie, once considered untouchable in terms of YouTube followers.

The Swedish Youtube star made a comeback after his fans banded together in various social media campaigns, but T-Series is catching up with PewDiePie again.
