E-mail adress

[Davide Giannotti]

I'm trying to fight spam like anybody else, and first thing is to remove mail 
adresses from every page on the internet.

A google search on my adress shows only 2 pages where i compare, they both 
come frome wine archive:

http://www.winehq.com/hypermail/wine-devel/2003.04.txt
http://www.spinics.net/lists/wine/msg08863.html

Is there a way to make them remove from there?

Just a suggestion: i'm conscious that mail adress need to be post into such a 
mailing list, but wouldn't be good to keep a script running that alter them 
into something like 'myname {at} mydomain' ?

Just a little sacrifice for everybody to help fighting spam.

Think about.. pls...

A better technique is to the CSS unicode bi-di attributes to convert

Mike Hearn

in the webpage to

Mike Hearn

in the rendered image the browser shows you. I came across this trick 
the other day and it's pretty neat. Boring old techniques like "username 
at host" are apparently useless against modern harvester bots, so maybe 
it's worth doing this.

Wow. You'd expect me to think of that one......

Still, that does not allow easy copy&paste, and it has unpleasant effect 
on web sites that actually USE bidi. Also, in order to be really 
effective, you would need to use RLO (else the strong directionality of 
the English letters would still make it left to right), and I'm not sure 
how widespread a support this has. Worst, this doesn't work for 
automatic clicks.

A better approach, in my humble opinion, is to use javascript. A simple 
method is visible in my site (a simple script that reorders the words, 
so that they do not appear as a full name anywhere unless you understand 
javascript). A more complex method is to RSA encode the email using a 15 
bit key that is hard-wired into the decoding javascript. This method is 
impossible to work around without actually running a javascript engine 
on the harvester, which would open them to all sorts of fun abuse by us. :-)
