I got a long text from this number saying they are a US Marine Special Agent currently in camp.  I too had some things posted on Craigslist.  I knew it was a scam.  No Marine would refer to themselves as a "Special Agent".  Now I need to figure out how to block them from my phone.

This number is being used by CraigsList Scammers.  This suspect is currently being investigated and tracked by the US Justice Department.  Ignore their amateur text messages!
