Description
This email cloaking method:
- is accessible for people browsing with screen readers (e.g., blind people);
- degrades gracefully for browsers without JavaScript;
- works just like a normal, clickable email address for browsers with JavaScript enabled; and
- requires no shortcodes.
Email addresses in the form email AT address DOT com are converted to a clickable version, email@address.com, if JavaScript is enabled. If JavaScript is not enabled (such as for screen readers), then the email address in the form email AT address DOT com is still readable to humans.
Screenshots
Compose posts with email addresses in the form email AT address DOT com.
The post should show a clickable email address. 
If you view the HTML source, the email scraping bots can only see email AT address DOT com.
Installation
Unzip the zip file into the /wp-content/plugins/ directory. Activate the plugin through the ‘Plugins’ menu in WordPress.
FAQ
- Won’t email scrapers figure out email addresses in the form `email AT address DOT com`?
-
In a test comparing the effectiveness of different obfuscation methods in 2008, the obfuscation method “Using ATs and DOTs” received much less spam than “Replacing @ and . with Entities”. Assuming that the 2008 test is an accurate model, this plugin should reduce over 99% of spam without compromising accessibility.
“CSS display: none” should not be used, because screen readers cannot read content styled with
display: noneeither. Reversing email addresses and using ROT-13 encryption are obviously not accessible, either. - Do email addresses that end with “.ca” or “.info” work?
-
Yes. Any email address with a TLD (top-level domain) of two, three, or four characters would work.
- Do email addresses that end with “co.uk” work?
-
Yes. Email address that end in “co.uk” always worked, but as of version 3.2, you can use the intuitive form: email AT address DOT co.uk.
- Something is broken.
-
Remember that the
ATandDOTmust be all uppercase (capital letters). You can also try going to Settings and change the replacement method to “Walk the DOM”, which is the new default for version 3.0+.If you still have problems, you can post your question in the forum and make sure your post has the tag
humansnotbots. Another option is to post your question here.
