Somebody who doesn’t understand cryptography might devise twenty clever-seeming amateur codes and apply them all in sequence, thinking that, even if one of the codes turns out to be breakable, surely they won’t all be breakable. The NSA will assign that mighty edifice of amateur encryption to an intern, and the intern will crack it in an afternoon.
Yeah, but then you really lose the capacity to deanonymize effectively. On priors, I can guess you’re likely to be American or Western European, probably like staying up late if you’re the former/live in Western timezones. I can read a lot more of your comments and probably deduce a lot, but just going off your two comments alone doesn’t make it any more likely to find where you live, for instance.
That would be ordinarily paranoid.
Even quantum cryptography couldn’t restore cleartext that had half of it redacted and replaced with “----” or something.
You can use whichever information you got to update your priors about what message was sent.
