Simple obfuscation of e-mail addresses

 Index   Obfuscation   Javascript   Sacrificial   Server   Filtering 

If you're limited to HTML there are some simple things that could help disguise your e-mail address, but if you want the link to work for humans it must be parsable by the browser, and any spambot worth its salt should be able to do the same.

Real protection requires server side code: CGI, ASP, etc., but this is not an option for many of us. Better protection is afforded with the Javascript solutions but some people prefer not to use Javascript.

Probably the best simple method is to use an image. This does require that your correspondents open up their mail clients manually rather than click a link, and then copy your address from the image. At least this is safe from current harvesters, though they are getting more cunning in their methods. To avoid the possibility of OCR in the future it might be a good idea to use a mixture of fonts. Remember though if a human can use your address from an image then another human can harvest it manually and add it to a spam list. A further point about image solutions is that one should also consider the limited ability implications. See further the Bobby portal. Perhaps an <alt> tag of "mail to jay gee at spell ess tee you are en eye dee ay ee end spell dot com" might do, as this would come out correctly in a web talker, however I'm no expert in this.

I used to have other techniques listed here but the simpler methods are not worth using now that spam bots are getting more sophisticated, some can even pick up on Javascript methods. If you want to see an analysis of the various simple methods have a look at section 3 on the Berkeley advice to students page.
