Keeping secrets from players

[MadMaxHellfire]

Let's say you came up with the perfect trick to spice up your setting and your players enjoyement of it throughout the whole ride, but it works only as long as it's a secret, something only GMs must know. Is it even possible, in the era of internet retards who think they're so smart and fun when they spoil others' entertainment?
I could come up with only two workarounds:
- Red borded pages (so they stand out and can be easily skipped), a big clear warning on the GM's book "If you spoil this you're just a retarded asshole"
- Coat the pages with a very reflective material so all the photos and scans are ruined, but it sounds extremely expensive and possibly not doable at all

You can only hope that the people do not spoil themselves. Or come up with your own stuff.
Other ways: Pricey limited editions make it more unlikely to be spoiled but no guarantees.
