I ran 'neoprint.php' on myself at Facebook in 2007 and immediately got a stern email about it... It was some script that collected info for responding to law enforcement requests. But after chastising me, the email said "I was gratified that you ran it on yourself". (as opposed to snooping on someone else!)

It was just a summer internship and FB was like 'only' 80 engineers back then. But they still took it seriously.

I think that's a little different. It sounds like neoprint.php is an internal Facebook tool for looking up data on Facebook users. So improper usage of it is a privacy problem for users. It's something misbehaving employees might run against celbrities, exes, etc. (e.g. https://www.gawkerarchives.com/5637234/gcreep-google-enginee... )

Otoh nmap isn't a privacy problem for users of Facebook (or any other tech company).

		Yea totally agree. Mainly just wanted to shoehorn in my own story about stern emails at FB! Also I think running nmap on your own development machine is totally legitimate. Lots of reasons you might want to do it.
