Text message received, inviting me to chat via webcam. I suspect it's a blackmail scam. They get you on video, then threaten to release any embarrassing footage unless money is paid.
Same as above. Text message saying "hi Jeff". I responded "who is this?" to which they replied to add them to my IM (screen name "bailychick24"). They added that they have no battery life to chat. Total scam.
Same as others have noted - I received a text message saying "hi Erin". I responded asking who it was (as I recently lost my phone and some contacts) and they replied to add them to my IM (screen name "aubreychick"). Delete and block!
