Hiding your emails on your website can be very tricky and the method should be chosen wisely. Yeah, its our war against email harvesters! Just now i have read the outcome of an interesting study made by Silvan Mühlemann. In his research he used nine different methods to obfuscate the email on his page. He created an email address for each method and was keeping track of the incoming spam for 1.5! years. Here is the outcome:
Amazing! The simplest methods using CSS had the best results. No Spam at all. There is just one question: How long will it take for the harvesters to adapt their algorithms to this research results?
(If you’re interested to see the detailed implementation of those methods just check the original article. I have skipped it.)
