My opinion doesn't mean much, but here it is.

IMHO, I think a computer geek gave in to temptation and tried to poke around the site doing the equivalent of peeking through keyholes. That may well be how the previous info was obtained, or maybe that particular info just whetted his appetite enough to try looking for more. I don't think there was any malicious intent, and the offense is not exactly punishable by the death sentence, but it sure is embarrassing when you get caught rifling around in someone else's drawers. The first response is looking for an excuse. The best thing to do is own up to poking around where you weren't supposed to and apologizing for it.
