How To Stop Spambots Harvesting Your Email Address

How To Stop Spambots Harvesting Your Email Address



It’s an​ unfortunate thing, but the internet certainly has its share of​ unscrupulous people. in​ my opinion, the worst amongst these are those that deploy software robots to​ roam the web and harvest email addresses from web pages. These addresses are then collated into huge databases and sold for the purpose of​ spam.

Now we all hate spam and anything that can be done to​ reduce it​ is​ very worthwhile. This is​ not rocket science and a​ basic knowledge of​ html and how to​ cut and paste will see you protected from the spambots. All we are going to​ use is​ a​ bit of​ javascript.

First, open Notepad or​ any text editor and then copy and paste the following into the file.

/* This script provides for a​ straightforward email address in​ a​ web page.
In your web page add the following:-
blocker("insert first part of​ email address") */
function blocker(name)
{
var domain ="yourdomainname.com";
document.write('' + name + '@' + domain + '');
}

/* This script adds a​ subject field to​ the email.

function blockersubject(name,subject)
{
var domain ="yourdomainname.com";
document.write('' + name + '@' + domain + '');
}

/* This script is​ for using as​ an​ "Email Us" or​ like in​ a​ menu system or​ on a​ page.
Insert the following in​ your web page:-
blocker2('First Part of​ Email','The text you want to​ appear on the web page');

function blocker2(name,text)
{
var domain ="yourdomainname.com";
document.write('' + text + '');
}

/* This script allows the adding of​ a​ subject, but also displayable text for a​ menu system. in​ your web page place the following:-
blockersubject2('first part of​ email address','The Subject in​ the email','The text to​ appear in​ the email');*/

function blockersubject2(name,subject,text)
{
var domain ="yourdomainname.com";
document.write('' + text + '');
}

//End of​ file.

Save the file as​ blocker.js in​ your document folders because this script can be reused over and over for as​ many different web pages as​ you like. You only need to​ change the variables in​ the script.

To get the scripts to​ work, there are a​ couple of​ things you need to​ do. I usually create a​ sub-directory for my javascript and actually call it​ that. Any javascript for the web page can be stored there. Save a​ copy of​ the file blocker.js to​ this directory and then edit all the variables to​ suit your site.

Now you need to​ allow the scripts to​ be called and the web page needs to​ know where they are. The easiest way to​ achieve this is​ to​ have the information in​ the section of​ your document. Before the closing tag, and assuming you have saved the file to​ a​ javascript sub-directory, insert the following line of​ code:-

(Insert less than sign)script type="text/javascript" src="javascript/common.js">(insert less than sign)/script>

You will just have to​ make sure that the path to​ the javascript sub-directory is​ correct for the document. This is​ simple if​ you use Dreamweaver as​ you can modify the template for your site and it​ will update all the pages. if​ you are using php includes, you will need to​ make sure that the path is​ correct from your header template through to​ the javascript directory. a​ little playing will usually get this sorted out for you.

One final thing that you should be aware of​ and that is​ that not everyone has javascript turned on. if​ a​ visitor hits your page and has javascript turned off then they won’t be able to​ see your email addresses at​ all. to​ resolve this, enter the following code just below the area where the email address is​ supposed to​ appear.

(Insert less than sign)noscript>

If you are seeing this, then Javascipt is​ not turned on in​ your browser and you won’t be able to​ see our email addresses. They are hidden by Javascript. You can either turn your Javascript on or​ alternately email us at​ youraddress at​ domainname dot com

(insert less than sign)/noscript>

Make sure you do not use the @ sign or​ put the dot in​ or​ even type the full email address properly. You will destroy all the good work you’ve done.

And there you have it. a​ simple piece of​ javascript that will prevent your email address being harvested by the nasty little bots that roam the web.
