Spam is website publishers #1 concern, we wanna share our and our visitors' emails to those who should have access to them, but don't want spam harvesters stealing them and sending garbage to us. A lot of techniques had been developed to hide our emails from these delinquents, while having them shown to real people.
And together with spam harvesting, on 15 June 2009, Matt Cutts, a well known software engineer of Google, announced that Google Bot will no longer ignore nofollowed links for PageRank, and now we lose PR/link juice for every link we add to our pages, even if we use rel="nofollow" on them. So, now we must hide links from Search Engines too!
I've been searching for an ultimate obfuscation solution for both emails and URLs, that would be user-friendly for me the content publisher, and for my visitors. I've seen a lot of solutions, some that inspired me, but none that would fit my needs. It was time to start coding :)
It doesn't use shortcodes, it works directly over HTML links, parsing and obfuscating them. By default it filters all texts in posts, comments, comments authors and text widgets, but you can manually use it anywhere you want.
Basically, Hikari Email & URL Obfuscator plugin searches for links that contain URLs and emails on their
The obfuscated string is then merged back by CSS to a readable URL/email text, so that human visitors can read it while spam harvesters and searchbots will not be able to detect it as a valid email/URL.
For CSS, it may revert the link string while PHP is building the page and then CSS reverts it back. Or it may add garbage text between the link, and CSS prevents this extra text from being rendered, so any user-agent that doesn't use CSS can't find the link but browsers show it clearly.
And, disregarding the used technique, we content publishers must do nothing different while building our content, just activate the plugin and it does everything else for us :)
I dedicate Hikari Email & URL Obfuscator to Ju, my beloved frient ^-^
