The Obfuscator stack works by taking email addresses, links, phone numbers or other handles. Using server-side PHP code, it cleverly converts each character into an HTML entity. When the webpage is viewed normally by a person, nothing looks any different. But when you view the source code, the original link appears as "gibberish" code. This spells bad news for spam bots and less intelligent web scrappers trying to harvest your contact details or other links!
