Doxxing (and the moral judgements attached to it) is a relatively new and not widespread concept.

You can’t just say “but this is doxxing” and expect people to know what you are talking about and also attach the same negative label to it as you do the same way you would when you call out murder or theft.

I personally don’t find “doxxing” that useful as a concept and as a guidepost to what I consider ethical or not. People who use the concept tend to be extremely zealous with at, to a point where anything identifying anyone is doxxing (and doxxing is to those people self-evidently unethical) and that just doesn’t seem useful or practical to me at all.

As to this particular case: if you create something as corrosive, destructive and powerful as Bitcoin society should know you. You don’t get to hide in anonymity at all.
