I should note that on several sites this isn't particularly true - for example, on Academia.SE it's pretty easy to know/guess and the questions are often about these marginalized groups.

...and when they make Hot Network Questions, the influx of people from Stack Overflow is highly correlated with an immediate drop in the quality of answers and essentially the ruination of the question, to the point that several high rep users, myself included, have asked if we could opt out of HNQ as a concept.
