Who called from 3105983675

I got this text message and so did several of my friends at almost the same time of day but from different numbers and different skype names:
"Hey...a friend of mine gave me your # ;P Said you were sexy!! lol! Add me on skype if you wanna chat madaam_slinky"

I just got a text exactly like that but from the phone # 660-223-695. wtf?? how did all these ppl get our numbers that's creepy.
