I get PDFs watermarked to me by their placement of sections in relation
to one another, their word choice in opening sentences of paragraphs,
and figure/image locations within the PDF. The idea being that the
content is the watermark, not some silly overlay watermark which is
fairly easily stripped out in most free operating systems.
