Where on earth did you get the idea that we're building data profiles of users when a) we explicitly tell you that we don't in multiple places in extremely clear language and b) the fact our users are demographically more likely to be members of marginalized groups is patently obvious to anyone who spends literally two seconds reading the Latest Things feed? Which is one of our spam-fighting tactics and so I spend probably more time doing than any person on the site except maybe our other garbage collector? Or reading the comments to official communities, where people are often very careful to provide the context for their feedback? Or just, you know, reading the site to see how people are using it? Seriously, our code is linked in the footer of every site page, you can verify that you completely invented this idea and are now getting upset at me over something you made up.
