Unfortunately, FunnelFlux Pro has no feature available that could hide your landers from spy tools directly -- usually such functionality is done on the landing pages themselves, rather than via the tracker.

In general, I wouldn't waste too much energy on trying to protect landers since its a cat-and-mouse game -- real users can see your landers, so other affiliates will eventually see them and can always circumvent any protections with enough effort.

One of the simplest things you can do is pass something from the tracker to the lander, e.g. a timestamp or ID, and then use PHP-based landing pages to check for this and serve different content if its not present. But, again this is easily circumvented if someone legitimately accesses your page through an ad URL.
