Well, I don't think of it in terms of finding trolls because there are better things to do with one's time than hunting for them... But not to worry, they will find you...

I've had a couple or four of the ankle biters here over the years... Most a5re just blowhards and they huff and puff and blow their own selves up on time...

Good luck with yers but know that he or she will move along when he or she is all blown out...
