Our efforts to reduce spam
Spammers. They’re a scourge. Particularly loathsome is the way they use automatic programs (called robots or spiders) to crawl around the Web, “harvesting” email addresses from web pages.
This means they’ll have to enter the email address manually into their email program, replacing
our shorthand with the real punctuation ("@" and ".") that makes for an identifiable email address.
Example: recipient (at) example (dot) com becomes firstname.lastname@example.org.
p.s. If you want to do the same on your site...
Instead of embedding a straight email link, as so:
which typically looks something like this: email@example.com
<a href="antispam_email.html" onmouseover="this.href='mai' + 'lto:' + 'recipient' + '@' + 'example' + '.' + 'com'">recipient (at) example (dot) com</a>
which would typically look something like this: recipient (at) example (dot) com
