Control of information definitely plays a major role in keeping the con successful. However, with advancements in technology and the emergence of the internet, the information is out there for the taking. I think it's getting harder and also getting easier to run the con these days. Easier because it is so easy and cheap to distribute lies and propaganda to the masses through online sources such as social media and "reputable" sources. But harder because if someone suspects they're being duped, it is often not too hard to find information to either confirm or deny their suspicion. You can actually do your own research and use your own logic and intuition based on your findings to formulate a truth that makes sense to you.
