That's what the article says. Are they sure of that? Who connected "anonymous" to Ventura? Jesse may be getting some "unjust profits," if someone other than Kyle connected him to the book.
I think the book used scruffy face or some such name. Later someone asked kyle if it was Jesse and kyle admitted it was.
The issue was this person said more seals should die and Kyle decked him. Jesse made this a much bigger issue then the book did.
