re: my recent boost (linked below)

mics (machine identification code) are nearly invisible marks most printers add to anything they print, as a means of tracking where each peice of printed material was printed from - down to the exact printer. not model, the individual printer

it's allegedly to curb counterfeit money, but obviously it can be used to connect material you print for, say, activism or political stuff down to the exact printer you used. if you're going to bureau en gros to print, or if you used a printer you bought, it can be traced to you

the @eff has some material that tried to identify printers that do or do not use mics, but it's no longer maintained:

https://www.eff.org/pages/list-printers-which-do-or-do-not-display-tracking-dots

makeuseof.com has another informative article on the subject including possible mitigations:

https://www.makeuseof.com/machine-identification-codes-printer-privacy-risk/

some mitigations they suggest include:

• https://h-node.org/printers/catalogue/en
  a list of printers that work with free software (which wont add the mics)

• https://github.com/dfd-tud/deda
  a tool to anonymize the tracking codes produced by your printer

these are both only useful to technically savvy people i think tho

anyway stay vigilant gang

MagicLike, 4 days ago to hosting

I got a DM about how to host a Website as anonymous as possible, especially viewed from the outside with as little attack surface as possible. I already threw a bunch of my ideas in the room, but maybe you can think of something I haven't thought of...
Please just answer to this post if something crosses your mind from security over hoster to the website itself, I will link it to the person.
