  • Just assume worst case that is always the case, because it is.

    For example: communication will technically always originate at yourself. This is at a small and big scale and includes not only your IP, network, carrier etc but also client attributes and characteristics which in whole always can create a very unique picture even with parts missing.

    Also a good example is the location data which recently was a source of news at least here in Germany. Because sharing limited pseudonymized data on mobiles in a single app makes you completely identifyable, showing you leaving and returning to your home address routinely/daily.

    Me, as an example, even though I live in a major German city can also easily be identified since there are many unique things of which I need just name a few and you could identify me if you have citizen and medical data, and a that takes are leaks. So of course I try to withhold a bit. Luckily even then half of what I am telling ist believed by many because it is unlikely or sounding like overacted.

    Anyhow, lots of reasons why even distributed data from you can make you identifyable or correlate things you wouldn’t like.


  • Life lesson: everything you put online could be exposed at some point. And the responsible admins can always (except for correctly encrypted things where you might need to trust they did this) see everything.

    So the best course of action will always be data minimization.

    (disclaimer: I’ve administered a lot myself and of course everyone should adhere to a legal framework and moral code. And of course we/you need the time to do your/our job.)
