> You can currently beat the system by posting an innocuous comment, waiting for it to be endorsed, and then after it's live, changing it to say something worse. We explicitly ask people not to do this. While we have no software for catching it, humans will notice, and we'll ban you.

Why can't you make the edited comment go through same cycle \process\flow as the original comment went through? that way you don't have to assume - no one will try to hack\fool the system
