This is perhaps a question with an obvious answer, but I wanted to make sure! If we have a nosy character, can they just spend 5ever reading all of the network posts that other people have made in the past? Obviously excluding ones that are marked as private or temporary.

Another question! Is it possible for characters to have some sort of personal text file that's only accessible by them, or is this the kind of thing that a character would need to know some amount of technological security knowledge to do? Similar to: on my phone I can write in my Notes app and this exists only on my phone (assuming I don't back it up anywhere) and unless someone physically takes and unlocks my phone they can't access it.
