Responding with hostility is likely to provoke a cyberbully and escalate the situation. Depending on the circumstances, consider ignoring the issue. Often, bullies thrive on the reaction of their victims. Other options include subtle actions. For example, you may be able to block the messages on social networking sites or stop unwanted emails by changing the email address. If you continue to get messages at the new email address, you may have a stronger case for legal action.
