Ladies and Gentlemen, it is the moderator's job to police the forums, not yours. If you have an issue with another patron, contact the moderator(s) for that forum and register your complaint. Taking action on your own will only land you in trouble. Also, ganging up on a 12 year old isn't very cool, at least where I come from.

Suggestion: if you are bothered so much by a patron, put them on your "ignore" list. Problem solved.
