I think "doxxing" has in some cases evolved from a sometimes-necessary norm in pseudonymous forums to a context-free knee-jerk reaction to somebody's details being out there.
I appreciate the norm when it allows people to safely be themselves among pseudonymous peers. Yes, by all means let's keep each other feeling safe. But like you, when somebody is doing business with the public, I think we should expect to know who they are. It seems insane to me that MrSquanchy69 can take in gobs of money, execute a rugpull, and have people saying, "bUt WhAt aBOuT tHeIr PriVAcY?!?" Public impact and public accountability go hand in hand.
