Terrible idea. Those emails are in no way solid proof and indeed appear to be tasteless jokes. You will lose this in the court of public opinion and come off looking illegitimate. This will make you look and PG look bad and accomplishes nothing positive. It's harassment and its' based on thin conjecture. Further, why do you feel that alerting some alleged bad person to their misdeeds is helping out? That's how accounts of interest go private, from enthusiastic half-cocked stalkers. BAD IDEA.
