Example - Protecting contact details
Stack by AJAX
To help protect contact details from spammers and automated harvesters, they can be added to a stack and the stack then added to a page using Universal Content Puller. Bots won't click to view the stack, so won't see the contact details.
Here the content source is a Stack - a stack can't be rendered by itself through any http request. No content transform is required, so that can be a simple Pass through. Similarly, content display can be a simple Plain.
In the Advanced tab, set the AJAX option to Ajax load when placeholder clicked and add a suitable message to your placeholder.
Unless the stack contains complex source such as a Google map, Sanitize output can be safe, then back on the Source tab at the bottom of the panel, this can be further otimised by setting the checkbox Do not load assets required by stack.
You can see this in action on my Contact page and the UCP block pulling the stack is repeated below.
