We do not have an attorney-client relationship. I am not your lawyer. The statements I have made do not constitute legal advice. Any statements I have made are based upon the very limited facts you have presented, and under the premise that you will consult with a local attorney. This is not an attempt to solicit business. This disclaimer is in addition to any disclaimers that this website has made. I am only licensed in California.
You listed the practice area for your question as "Education". If the cyber bullying is on a school website or related to something that happened at your school, in addition to Atty. Sargeant's comments I would add that all Massachusetts schools are supposed to have anti-bullying policies. If the events or comments are school related and go beyond the First Amendment boundaries that Atty. Sargeant mentioned, you should report the cyber bullying to your principal so that it can be properly investigated.
