John Doe mainly posts at 6 or 7 o’clock in the evening – and a couple of times at 3 in the afternoon. So! Is he a college student that gets home at 3? Or is he a worker that has his afternoon tea break then? The rest of the time is after dinner, I assume when he has got home from work/college. He is probably posting from the US or Canada then, or the time zone would not work – although we need to check this out more thoroughly.
