Wow, I believe it. We didn't have so much a rogue situation, but you really do have to constrain their actions to just what you wanted. I tried to find the source but there was some YouTube video I watched where the guy made this good comment about creating GUIs where you have to put a real emphasis on preventing users from doing things you do not want them to do. You can't always focus on features but also constraints. I really took that message to heart after experiencing some of the human unpredictability found in building up training data. It made for some interesting payment debates to ask them to redo some work that was incomplete. Fun stuff.
