FreeWall® can be used in Pure Anti Ad-Blocking (or PAAB) mode. In this configuration, the content is always immediately revealed as soon as the relevant code is loaded up from the Rezonence servers. If an ad-blocker prevents the code from being loaded, the content remains hidden and a message is shown instructing the user to turn off their ad-blocker.
You should be able to see the entire article without obstruction. If you turn on an ad-blocker you can see how the page renders when you refresh your browser.
This mode of operation can be used to protect a whole site against ad-blockers while only selected pages actually show the AdUnit.
