1) Startups (some anyway) tend to get a lot of media attention
2) Startups have fragile reputations while they are making a name for themselves
3) Startups tend to have more personal relationships with their customers than more established companies
It follows that startup personalities will encounter stalkers of various sorts. Articles about a potential consequence of this, discussions of how to deal with it and so on seem as on topic as "tips for personal productivity", "how to deal with office politics", "Prosecutorial overzealousness", "copyright" and other recurring themes here.
Further, speaking a bit more generally: People here are pretty prone to living huge amounts of their lives online. One of the dark sides of the internet is that it has been a great stalking enabler, and those of us who spend a lot of time online in forums, etc, can be at greater risk for general muck-raking, since the volume of stuff known about us "on the internet" is larger.
