Who called from 8563930796

Got a message, knew my first name, responded by asking who it was but no response...notice the number listed here

Same thing. I got a message, "hi sherri..."
didn't recognize the number so I googled it.
Saw that other people are getting similar text messages so I just ignored it.

I don't recognize this number, person knew my name in a text

Same as above, knew my name, no reply to my text.

Yep. They texted me "Hi Mike". I replied 'hi'. then they wanted me to add 'textchick60' to yahoo messenger.
