How It Works

Spam programs scan the internet and look for e-mail addresses that are displayed on web sites. By using this app, you can disguise your e-mail address using JavaScript that is unlikely to be decoded by most spam bots. Normal users with JavaScript enabled will see your e-mail address as a clickable link because they are viewing your web site through a web browser.

This email anti-spam encoding service ("the System") is provided as a courtesy only. It allows you to encode your e-mail address using JavaScript, which is a method that some believe will prevent the e-mail address from being harvested on the internet for the purposes of sending spam. This site owner does not provide any guarantee that using the System will actually result in a change in the amount of spam you receive.

You are not authorized to access or query the System through the use of electronic processes that are high-volume and automated. By using the System, you agree to abide by the following terms of use: You agree that you may use the System only for lawful purposes and that under no circumstances will you use this data to: (1) allow, enable, or otherwise support the transmission of mass unsolicited, commercial advertising or solicitations via e-mail, telephone, or facsimile; or (2) enable high volume, automated, electronic processes that apply to the owner of this web site (or its computer systems). The compilation, repackaging, dissemination or other use of this data is expressly prohibited without the prior written consent of this site owner. You agree not to use electronic processes that are automated and high-volume to access or query the internet address lookup system except as reasonably necessary to register domain names or modify existing registrations. This site owner reserves the right to restrict your access to the System in its sole discretion. This site owner may restrict or terminate your access to the System for failure to abide by these terms of use. This site owner reserves the right to modify these terms at any time, and your continued use of the System after modification indicates your agreement to abide by these terms.
