I've been using academic.stackexchange quite enthusiastically during a rough postdoc devoid of mentorship. However, since I am a young researcher and since some of the questions I want to ask are rather sensitive, I am careful about what information I disclose, my field being one of them. My specific field is small, and it wouldn't take much effort to figure out who I am if I disclosed my field on top of the other personal clues I've given in my questions. I've noticed others doing the same, probably for similar reasons. However, some would-be-answerers rather aggressively insist that I disclose my field in order to answer my question. I'm wondering if there is some way around this-- i.e., how to guard my privacy while still offering enough information for an apt answer?
I've already hidden other SE groups that I'm a member of, and changed my username (but I doubt that would deter an eager detective; at some point SE was even storing old usernames publicly, and @ tags to old usernames remain). I completely understand that practices change from field to field (and even from subfield to subfield). Yet there are real privacy issues at stake. I'm even considering just deleting questions after I get a satisfying response, but I know that defies the point of SE.
This question is related, but does not deal with privacy.
