Times like these I have to remind myself that it's never the right thing to do to punch a Nazi, but boy would it feel good (metaphorically; literally physically punching a Nazi/anyone is probably not something I have in me). Honest question for the folks of HN: would it be ethical to violate these Nazi's privacy, de-anonymize them, and contact their family/employers based on this leak? I think the easy (and probably correct) answer is no, but I'm curious if anyone has a nuanced view here.
