Metro-Nashville Public Schools is investigating anonymous Instagram accounts set up for the purpose of degrading and criticizing the appearance of students.
The trend has been seen elsewhere in the United States, but just turned up in Middle Tennessee over the last few days.
Officials in Rutherford County Schools sent an alert to parents on Monday warning them of the potentially dangerous cyberbulling.
The Instagram accounts are being set up anonymously and show pictures of female students and encourage others to make degrading comments about their appearance.
MNPS spokesperson Meredith Libbey says the district is taking the issue seriously.
"Obviously this is mean-spirited, it is a violation of our code of conduct and in some cases we understand it may even be illegal activity," said Libbey.
MNPS officials are asking parents to monitor their children's social media closely and notify their school principal if they have been directly impacted. MNPS has posted some tips on the district's Web site.
