Here we go...
Here is a script which you should copy/paste to any text editor and save as *.html file.
When you open it, it will generate 5000 (easy to change number!) non-existing e-mails.
Copy/paste this e-mails to any text editor and save as *.html again.
Then, make an invisible (one little dot of the background color) link to this last html on your site at the place where it is almost impossible to click.
Spammers are using software to spider your sites and they will probably receive those 5000 emails. After that they will try to send spam to it and... here is the point... NOTHING WORKS out!!! The time and traffic are spent but oh my... NO RESULT!
Spammers are fucked

lol
