Ah, that's an interesting point. And not just 4chan. Imagine if someone posts your license # along with some rant about how you were a jerk to Reddit or Digg. Let the mass flagging begin! This already happens with polls, or yelp or whatnot. Even if you were in the wrong, you could get punished way out of proportion.

I think there is already nothing to prevent that. A single 4chan insider -- every insurance company probably has at least one -- could wreck your rates. They could probably also figure out how to send forged police reports to the insurance companies if they wished.

I guarantee you they have some code like

if licence == Philip_Inghelbrecht: pass

Basic human decency, covered with an icing of crossed fingers?

Read his post again, and pay close attention to the part that says 4chan

Ding!
