You're in luck! Alexi had his thoughts on this written down in his biography. I listened to it as a soundbook, so I can't tell you exactly where it was or the precise wording. The hatecrew thing came from a crewmember that signed a tag on some of their stuff or something and Alexi thought it was cool. Deathroll comes from payroll. Thus a list of people to be pit to death by the hatecrew. Might have gotten this wrong, but I'll get a hardcopy of the book someday soon and will be able to verify.
