No hostname -- not so cloaked.

Screw Facebook -- You got their IP ranges for compliance/enforcement? Maybe, they are using these "not-so-secretive" IPs to surreptitiously track user behavior?

At any rate -- these wunderkinder are not as smart as they think they are ... have fun

That is what you get for scanning or scraping my servers {=O=} pwnd!

these things are complicated.
all i kow is scan an ip address using nmap and find open ports and extra info like that.
