[Spooks] Need help identifying something weird

[Dan Malloy]

I heard the same srange message on my cell.  I don't know if it is
real, or if the NSA is watching whoever calls it.  Craigslist has
pulled it as of when I checked it this morning.  They said they
pulled it on the 8th.  The question is : why would a spook use a
landline number that could easily be traced?  If the message takes 7
minutes to run through, that's more than enough time to find the
caller and the destination.
