Laura Iacovacci, a 16-year-old junior at Paramus High School in Paramus, N.J., was suspended last month after teasing a classmate during school and implying he was gay. While at home on her suspension, she posted some comments on MySpace -- including a post in which she commiserated with a friend who was paired with the boy for an activity in gym class. "Poor u ... not fun not fun," Ms. Iacovacci wrote on the page. The comment has since been deleted.

Ms. Iacovacci said that when she returned to school, she was called to see the principal, Lina Gudelis, who showed her a fat stack of pages she had printed out from MySpace. Ms. Gudelis suspended Ms. Iacovacci for three more days. She wrote in a letter to Ms. Iacovacci's parents, "Please be advised that should Laura continue to participate in harassing behavior, either verbally or in writing, including websites, she will be suspended and may be transferred out of the classes she shares with the recipient of the Harassment."
