You're changing the subject from how you misrepresented why Snowden ended up in Russia. I won't engage further with someone acting in bad faith.

Your comment is indeed very telling. He ended up in Russia because the U.S. revoked his visa while en route to Ecuador so he was forced to live in a Russian airport for 6 weeks.

#55The "print and scan physical papers back to a PDF of images" technique for final release is looking better and better from an information protection perspective.
if really paranoid, I suppose one could run a filter on the image files to make them a bit fuzzy/noisy

Do you have a suggestion for a better routing? I surely can't. How should he have gotten to Ecuador? (Which, btw, is not a US adversary.)
As for your "drop off" conjecture, we have no evidence that happened, and unless you are attached to the "Snowden was black-hearted liar" fabrication, we can all read https://en.wikipedia.org/wiki/Edward_Snowden where he says he did not do that, and explains why:
> In October 2013, Snowden said that before flying to Moscow, he gave all the classified documents he had obtained to journalists he met in Hong Kong and kept no copies for himself.[110] In January 2014, he told a German TV interviewer that he gave all of his information to American journalists reporting on American issues.[57] During his first American TV interview, in May 2014, Snowden said he had protected himself from Russian leverage by destroying the material he had been holding before landing in Moscow.
I take it you believe he lied, and during the last decade-plus his nefarious actions and additional secret files never leaked.
Would you care to explain the basis for your belief?

#57These PDFs apparently used the “incremental update” feature of PDF, where edits to the document are merely appended to the original file. It’s easy to extract the earlier versions, for example with a plain text editor. Just search for lines starting with “%%EOF”, and truncate the file after that line. Voila, the resulting file is the respective earlier PDF version. (One exception is the first %%EOF in a so-called lin…

Note that all (edit: color-/ink-) printers have "invisible to the human eye" yellow dotcodes, which contain their serial number, and in some cases even the public IP address when they've already connected to the internet (looking at you, HP and Canon).

I've got a black and white brother printer which uses toner. Is there something similar for this printer?
excellent choice, that's what I am using. Also it's Linux / CUPS compatible and without a broken proprietary rasterizer.

Why not just make screenshoot of every PDF page?
It could still be identifiable, for example if the document has been prepared such that the intended recipient's identity is encoded into subtle modulation of the widths of spaces.
