Liked the reasoning, deduction and logic of this dude portayed, alas I found it a little sloppy in his execution. Actually it's not too much of burden or too much work given the state of affairs with social networks and people. Added to the the endless need for attention 95% of woman have, and the massive narcisistc tendencies they carry during their prime years (and not so prime), so it actually requires very little effort to do this doxing, so not impressive in ayones book.
Found the guy little over the top @24:00 minute mark entering the womans apt. to know more of her, he could easily find how to hack that stupid computer of her, without physically irrupting in her apt, but that is the thing with this series they want to convey the sense of a desperate but intelligent male stalking a pretty bitch, for me he is an over invested stalker a little clumsy, when I was seeing this shit on the back of my head always remembered --those things are the ones the women do when we have our shit together-- Meaning the stalking and shit

So take this series with a grain of salt
