3,000 pages? Why would it need to be that long? Isn't that kinda extreme? I don't think any average person would even want to read that, and making a copy of that would just seem wasteful of paper... Couldn't they make it shorter?
Another theory is that the person in question had no idea what the document looked like or where to find it, and just made up the 3000 page story in a hope to scare off the person asking for it.
