They generally have the same stuff as any other average bootlegger on the street, just because it's a mafia operation doesn't really mean they get special content, but they might. Maybe try wikipedia :dabs: But yeah, they could be scene releases, or maybe they've got their own sources for their bootlegs, which is possible since it's quite profitable. I guess you could go ask one of the guys on the corners in New York, they might know.
And I don't think they've got a website... This isn't Netflix you know
