Spam proof email
4th July 2002
Today saw a useful thread on Webdesign-L about hiding email addresses from spambots. Some of the points raised:
- Javascript encryption makes addresses inacessible to anyoen with javascript disabled, not just spambots.
- Form based solutions help avoid ever exposing your address to the open web.
- An english description (mail cs1spw at bath dot ac dot uk) is a good solution, but may eventually be parsed by spambots as well.
- If you go down the javascript encryption route, adding an english description in <noscript> tags can make your address more accessible.
- An image showing your email address is spambot proof, but does not solve the problem of how to hide addresses that can be clicked on.
- A lot of users with webmail do not benefit from mailto: addresses anyway, and would prefer a form.
I have restructured my contact page to take these in to account.
