To avoid being listed on CD-ROM's with millions of addresses sold on Internet

With his authorisation, I reproduce parts of a very sound email Christian Mercat sent me (with my own grain of salt, and my own approximate translation, of course)

Advice by Christian Mercat

I give you a few of my techniques (even if they did not avoid me being listed in several CD-ROM's under an email address I can afford to loose):

when you write in forums, give a false email address like:mailto:kri@frok.dog.net <- remove the animal. So, a human speaking English can understand and remove the .dog part while a dumb robot will only collec a lousy address.
[YR: People often use NOSPAM instead of dog; but, since this became quite common, it's no longer infaillible against some of the smartest robots.]
on your web page (I think I was caught just there. [YR: like some many other people]) or in forums, use an email that can easily be dropped without a consequence (at a free redirecting site) like mercat114@yahoo.com, that will be changed to mercat115@yahoo.com when the first attacks come. This only works if your real address is kept secret and only for the eyes of people you know very well.
when writing a bulk email, for a petition or a small ad, to a list of known people, always put all the addresses in Bcc: so that your friends will not be bothered
- receiving a heavy email with a large unreadable header
- seeing somebody on the list reselling the address. I know of cases where some of the correspondants forwarded the email to a mailing list (at the University) where somebody snatched it and made monet out of it. Each time I receive a large list like this, I inform the sender about the risk in order to avoid him to do it twice.

[YR: Furthermore, if this is the list of your Customers, you certainly don't want to give for free to your competitors who may happen to read the email!]

Hold tight,
