What's the unethical component to this? To me, it all depends on what you do with this information. If you use the demographic info simply to understand your users and improve the service for them, then why is that bad? Perhaps you realize after looking at this demographic info that your assumptions about your userbase are wrong and you need to adjust your offerings or cater to a minority that you neglected. On the other hand, if you use that info to discriminate, then ya, that would be unethical. And if you think giving this list our to MTurkers is unethical, then I have to ask why as well? I think you have to ask yourself that by giving away this information, does it open up your users to vulnerability? Would you be enabling unethical behavior on the part of someone else, thereby making you guilty by association? For the record, I downvoted you because with a subject this sensitive, you should explain your position...not just make a quick, semi-accusatory statement. We need more comments with substance on HN.
