ARCHIVE / What options are there for email obfuscation?
One means is to encode the characters using HTML character escape sequences. This option will work for most email crawlers but not those sophisticated enough to have a preprocessor to decode escape characters.
A third option is have the mailto: link in an embedded file, such as a Flash piece. This method works but is problematic in those rare cases where Flash is not supported and when there are multiple or variable email addresses needing to be displayed. It also increases the downloadable size of the page and time required to display the page.
