Thank God the PDF format does not readily lend itself to this type of abuse. I disagree with the idea that PDFs will widely used for SPAM. It simply takes too much time and too many clicks to access a PDF for it to be a viable solution for SPAMmers. Also, a PDF cannot be embedded into an email (as far as I know w/ Acro. 7). SPAMmers would lower their click-rate even lower than it already is by using PDFs.
