Whack 'em....oh I forgot you can't do that. Unfortunately, I have NO advice. We went through something similar a few years ago. One ringleader with a bunch of ringlets. It was awful and I hated...yes, hated those children. Finally, thankfully, it passed...probably on to another victim.
I wouldn't be above contacting an attorney and having a "nice" little letter written to the girl's parents. Sometimes just a letter gets their attention.
I'm sorry...wish I could help you.
