Who called from 4702051816

I had a sleezy message on FB, leaving this number for me to message.

This is a scam to get your tel number that they resell.
this one is from Atlanta GA.
Have got same scam from NY area.

received an email on my hotmail account saying they saw my picture on FB and wanted to connect with me, gave me this number to contact them.  well I do not have a FB account so I know that is imposable and even if they did see me so where on the internet, I would never want to me someone like that.  Know it is a SCAM of some kind.

The 2nd-4th messages above are identical to those on http://www.whocalled.info/phone/1-470-205-1816.  What's going on?  Who's scamming who?

I got same thing. It's a scam.
