I also got an IM telling me to call this number. The IM responses when I typed back were quick and canned - like it was either automatic or the person was copying and pasting. Said I could get my college degree in practically anything and it only takes a month.
I just had an IM pop on on Yahoo messenger with this same thing. But the weird thing is it came across as being from one of my friends. I quickly realized it wasnt him and text him to ask if he was talking to me and of course he wasnt! He said he recieved several calls from other friends asking if he sent the message. Anyone call the number and find out what it was?
