Why http://address-protector.com? This server encrypts your e-mail address in a way, that makes it impossible for automatic programs (so called "address harvesters"), to find your clear-text e-mail address on web pages, and to consequently use it for sending you unwanted commercial e-mails (so called SPAM). How is the E-Mail Address protected? To decrypt the e-mail address, the user has to prove being a human and not a machine. That is done using the CAPTCHA service of http://captchas.net.
