Got a text message from this number in response to a Craigs List ad I posted to sell a motorcycle.  The text read:
Hi, about the bike ad - my boyfriend want one same kind as this <<pic-att>> http://pix-send.com/?photo=297MBF.  Is this the same type?  Buying him 1 this week.

The link is a site that requires the Gimp Photo Viewer, which I Googled. I read posts that claim the Gimp Viewer may be infected with a trojan or virus.  Also, number is in California, and my ad was placed in Pa.
