... doth protest too much.

Here's the disclaimer from a recent piece of Brazilian spam:

This message is not a spam, given that it's only being sent once, and also it contains a way to be removed, it's a normal email like so many others that you receive, we're not invading your privacy and sending an email isn't a crime, since it doesn't contain messages that can cause harm to the user. If you want your address to be removed from our list, it's enough to send a mail to ... with the title (subject) 'remove', for your email to be removed permanently from our list. Please excuse us if we've bothered you with our advertising e-mail. Thanks!

The logical flaw (aside from the fact that it most definitely is a spam) is that if they were really only going to send the message once, there'd be no need for anyone to remove themselves from the sender's list: clearly, they plan to send more in future.

I was a little disturbed by how easily I could read the disclaimer: apparently a steady stream of Brazilian spam has given me a good grasp of written Portuguese. I guess it's not a bad thing, but next time I think I'll just buy the book and tapes, thank you.

(And yes, I know that the title of the post is a misquotation — but it fit better than the correct version.)
