Another issue is that if you give out even that bare minimum info, and it somehow gets out to the public threads (which I've seen happen time and time again), then you also risk anonymity by way of a loved one or someone who knows the person in real life seeing that little bit of identifying info, and then connecting the dots and filling in the rest.
That's why I'm not giving a date or making it known exactly when I'm going, people who know me will eventually know that date, and my method, and perhaps be led here (not by me, but by the circumstances of the death) to try to figure out who I am and read all the shit I wanted to remain anonymous, perhaps even posting themselves and doxing me postmortem (which would be disgusting and quite frankly, evil of them, but I don't trust a single one tbf).
They could look for users who caught the bus the same date I did, then even better-a first name, a general location, and that would be way more of a starting point to Sherlock Holmes my ass than I am willing to offer them.
