Email address was leaked from Launchpad

Hi there

I generate a new email address for every place I sign up so I can track where my email addresses get leaked. Today I got several spam emails to my launchpad email address, despite the email address set to not being disclosed to others:

Here's a copy of the spam email:

Dear Partner,

With so much respect to you and with a good heart and the need to establish relationship with you I write you. I beg you not to regard this as a joke or as a contact to inflict harm on you. Please do consider this mail as one sent from a man who above all seeks peace, confidentiality and your assistance.

I have a proposal to make to you that will not bring harm to you in anyway. This proposal will bring immense financial gains to you and also put you in a position to manage a sizable financial portfolio. Note that I am contacting you because of the confidentiality I want to maintain in this regard. I would have contacted diplomatic affiliates in Europe, America or the Far East Asia but this issue requires contacting an individual that can handle issues quietly without making it public.

I am Mr. Joseph Ofori Teiko staff of CAL bank Ghana.I am contacting you in respect to a financial portfolio of Ten Million United States Dollars (US $10 Million) deposited in a security firm whose depositor died in mid 2007. As the Director, Treasury (International) Operations Unit,

I want to assure you again that this will not put you at risk or in danger in anyway. It is a quiet arrangement that will be strictly between me and you. I will introduce myself fully to you and give you the details of the proposal once I hear from you.

Kind Regards,
Mr.Joseph Ofori Teiko
