This is not about slander or libel or fraud. It's about some guy claiming he has an award he doesn't have. It is making lying a crime, even if no harm (other than believing the lie) comes from it.
You guys really want that? You want everything anyone says to be subjected to a Truth Squad? You want the government to have the power to force us to always tell the truth? What's next: It's illegal to lie when someone asks if this dress makes her look fat?
Is this guy scum for doing this? Of course. That's not the issue. Don't be blinded by the dislike of this guy to open the door to having anything you say subject to government oversight.
The first amendment is meaningless if we only protect speech we agree with.
