Obscure Stack
Generate clickable email addresses and phone numbers that trawling robots won't be able to harvest.
Description
Hides visible email addresses and phone numbers from trawling robots. Trawling robots visit your pages every day, some collect email addresses and or phone numbers to be used for spam. Stop them now.
So you would like to display a plain email address or phone number as a text link on your page, but your worried about trawling robots harvesting them. You should be..! Harvesting robots visit your site all the time. This stack will prevent them from obtaining email addresses and phone numbers you include in your page, and stop that resulting in spam.
Demo
Try clicking the text links in the paragraph to see them in action.
So here's a paragraph of text that contains a very visible email address link : ObscureMail, and contact telephone number link: ObscurePhone. but because we have used Obscure stack, the email address and phone number can not be seen by trawling robots, trying to get these gems to spam you.
So what's happening in the demo paragraph above?
Here is a screenshot of this demo in the backend. You can see the demo paragraph text and two obscure stacks placed below. One for the email address and one for the telephone number.
In the paragraph we have added the text keys for each obscure stack. When the page is previewed or published, the text keys are replaced by the email address or telephone number respectively.
This only happens when the page is loaded into a javascript enabled browser. Until that point the private data is stored in a remote isolated php file safe and sound. So only humans loading the page in a browser will ever be able to see the private data.
User Settings
A comprehensive overview of this stacks user settings.
In email address mode...
The email address you'd like to be displayed and linked to.
This is where you enter the text that becomes the subject of the email when the email link is clicked.
If you add any text here, instead of the email being displayed as the link, this text will be displayed as the link instead. Clicking the link still generated and email that will be sent to the email address.
Now this should be unique, contain no spaces, and be only alpha numeric [(a-z)(0-9)] characters.
Using words like "email" as the key really is not going to cut the mustard, as this word may well appear in your page in places you do not really want it replaced with an email address.
Use things like "obscureEmailAddressOne"
This not only guarantees it will not be found anywhere in the page other than where you purposely place it, it also has meaning.
You can add as many obscure stacks as you like to a page, but each must have it's own unique key.
You can use the key of any obscure stack, as many times as you like throughout the texts of your page. Each time the key is found, it will be replaced with the email address you entered into that obscure stack.
In email phone number mode...
The phone number you'd like to be displayed and linked to.
If you add any text here, instead of the email being displayed as the link, this text will be displayed as the link instead. Clicking the link still generated and email that will be sent to the email address.
