The thing that sticks out in my mind is that no "warning" is going to allay curiosity. If technological progress continues unabated, we won't have to keep nuclear waste on the planet for 10,000 years because we'll have safe, economical ways to dispose of it in interstellar space before then. We need the 10k-year warnings to account for the situation in which our civilization declines, is forgotten, and later humans come upon it. So, let's say that it's 6500 AD and what we are now is an ancient civilization. If you come upon a sign that says something like this (from the article): This place is a message…and part of a system of messages…pay attention to it! Sending this message was important to us. We considered ourselves to be a powerful culture. This place is not a place of honor…no highly esteemed deed is commemorated here…nothing valued is here. What is here is dangerous and repulsive to us. This message is a warning about danger. What are you going to do? Some of us would avoid it, but there are others whose curiosity would lead them to explore. Think about it: a warning from a 4500-year-old advanced civilization. How does that mystery box not get opened?
