In order to overcome their lack of inspiration, they performed a blood ritual in prayer to their ancient religion by slicing open their palms and pressing them together. When Mark awoke in his apartment the next day, he had no memory of what happened during nor after their ceremony. The only remainder from that night was a music file on his computer from an unknown source, simply titled: "Blood Cultures"
After experiencing several nightmares consisting of ghoulish (yet sexy) Dementor Pirates compelling him to upload the file to the internet, he finally caved and obliged. The music grew, developing like a virus, seemingly taking on a life of it's own, eventually bleeding into our reality. He was no longer in control.
To this day, Mark Zuckerberg has never publicly denied his responsibility in the incident.
