My Facebook Shim
In response to the Facebook Link Shim I have decided to create my own. This is in the form of an Alert() box that displays when a Facebook link is clicked explaining the you are about to leave the site to a potentially "Maliciious" or "spammy" website and that your personal data may be exposed if you visit that site, Facebook in this case.
The code on this page was based on the adaption of my page demonstrating that W3.css Modal - Login Dialog.
The buttons either close the modal or take the visitor to a new page or website.
Sending a modified (Restricted) Header
The Ok button needs to send restricted referrer information to be the same as Facebook, but in my case this is not important as I am not trying to control digital marketers from getting too much information!
To test this I would need two Google Analytics properties on different domains, which I have but is it worth all the work?
