Any insight based on histogram of the timing of this person's posts, particularly ones responding to a just slightly earlier post? (ie was clearly awake and not an artificially-delayed response).
Krebs knows about this timezone analysis technique, wonder if he didn't check this or it was inconclusive?
Is that effective for people who aren't literally being paid a salary to do this stuff 9-5? A lot of people who spend too much time on computers have totally out of wack sleep schedules that would look like they're operating from very different timezones.
You can also schedule your posts, commits, etc to go out at some fixed hours each day.
You can, but a lot of these pattern analyses work out because people get sloppy and overconfident over time, and don't use these measures even if their lives are on the line.
Police raids in long sieges happen ~ 3:30-4:30am
People have wacky schedules but it's about when you never work
You could do an analysis on HN comments.
It's very hard to fake, you'd have to schedule on all channels. For instance don't look at all of a users HN comment's just ones posted less than a hour after it was on the front page.
I always set the time zone on my PC to a fake one. It cause's havoc sometimes and it's not even close to enough. It's hard once someone is after you.
