I bet it's tokenadult. I do not have any other proof than the fact that I immediately thought of that username when I saw onetimetoken. :-)
Evidence that the comment does not come from my keyboard:
I would never write a ponderous sentence like "I fully agree with the sentiment that inspires your statement" as the opening sentence of a post.
I wouldn't write "Without even noticing it we are whoring out our privacy and intimate patterns," because I consider "whoring out" a crude expression, too crude for the polite, learned conversation I expect on HN.
The phrase "it requires a mindset and workflow not entirely dissimilar to those of spies" reminds me of George Orwell's "One can cure oneself of the not un- formation by memorizing this sentence: A not unblack dog was chasing a not unsmall rabbit across a not ungreen field." I may occasionally write like that, if I am composing a sentence as I type, but I try not to.
He is not me. I think he is male.
