Extortion by Email Spam

Spammers are getting desperate. I received the following email a few days ago, which somehow got through Gmail’s spam filter:

From: “germes”
To: “donncha” <.....>
Subject: RE: Hello

Hello You received this message because this is an email list for mass mailings. We analyze the list and remove a lot of email. pay you $ 2 or 2 euro, and we will remove it from the list of spam Email newsletters.

I presume they meant to say that I pay them to remove my email address from their mailing list rather than the other way around!
