The September 7th, 2012 receiving amounts reveal: "gnp.Kz5HB/moc.rugmi.i//:ptth"
Reversed gives the url: http://i.imgur.com/BH5zK.png
When scanned leads to: http://www.sendspace.com/file/m6crjs which leads to a file that has been deleted.

The September 9th, 2012 receiving amounts reveal: "tqvbn/oc.x//:ptth"
Reversed gives the url: http://x.co/nbvqt which just redirects to GoDaddy.com
Even "fixing" the url to be http://x.com/nbvqt leads to a page not found.
