Encapsulating e-mails for usability and spam protection

Tuesday 26 October 2010 1:15:03 am - 5 replies

Introduction

At the end of this tutorial you will have a new way of encapsulating e-mails avoiding crawlers to collect and use them as spam. Users at the frontend will have a well-known e-mail sequence to click thus avoiding confusion. Developers will not sacrifice usability versus spam-protection.

Eirik Alfstad Johansen	Thursday 28 October 2010 4:33:22 am The title of this article is slightly misleading. Shouldn't it be "Encapsulating e-mail addresses..."? Sincerely, Eirik Alfstad Johansen http://www.netmaking.no/
