I zipped up some nasty images (war/executions/suicide/be-headings, etc) and mailed it to the hacker, via that email...
It seems that when you reply, it goes to the real MT Gox... that is if the response I got is really from the MT Gox people...
response from Mark Karpeles:
what would be the point for something like that?
even if it got to the "right" hands what purpose would it serve? revenge? aaargggghhh take this picture ...
as bcpokey wrote its 'easy' to fake all of the email headers.
lets face it. sh*t happened. lets move on.
