The prevalence of having experienced cyberbullying was 54% among subjects who used Internet >3 hours/day compared to 39% among those who used 1–3 hours and 30% among those who used <1 hour. In terms of practices to cope with this, most students chose to ignore it and not share information with their family or teacher.
