protecting landing page

[deppstar]

Lately I found one of my original Lp ripped and used by a wide aff network for one of its best offers. Flattering but together with finding today an old thread tutorial on spytools where the example was "my offer" my question to the community can't be other than: how do I protect my work from being cloned from all the actors of this unregulated young industry called "aff mktg"? I don't expect 100% stealth mode, that comes from experience and well deserved sweating, but at least 30 to 50% as it's impossible to be profitable without that. It's now obvious.
