I feel like making it explicit that I fully endorse people staying hidden, if that's what they want to do. Anything I say that seems to the contrary is just trash talk in the spirit of competition.
I agree that it kind of sucks that we can pretty accurately deduce how much people are making in rewards, when those people have expressed a desire to protect their privacy.
Maybe there could be a lower stakes contest with a leader board that is opt in and only a fraction of the rewards pool goes towards it.
