Printing (even text) is also a risk: It's very likely your printer is secretly adding marks to the page that contain its serial number and the current timestamp. [0]

Meanwhile Microsoft (and Apple) have "telemetry" harvesting those serial numbers of all internal and external devices you've ever had connected or reachable. Then they link them to your MS/Apple account, IP addresses, and the extended social-graph of all computers that were ever in the same room or shared the same bluetooth speaker.

In short, your "anonymous" flyer critiquing The Regime and depicting Dear Leader as a clown could lead thugs straight to your door. Or to the door of whomever you're staying with.

It's most likely how the FBI caught NSA leaker Reality Winner:

> Both journalists and security experts have suggested that The Intercept's handling of the documents, which included publishing the documents unredacted and including the printer tracking dots, was used to identify Winner as the leaker.

and then in few years a new mono-mustachioed or mono-browed leader will emerge who declares memes a blasphemy punishable by death and will call up all the telemetry gathered to punish all involved.
