If you really want to sue them, it can be done no matter where they live. It is just a matter of coming up with the retainer. We handle multijurisdictional lawsuits all the time, for example we nailed a defendant in Egypt for similar activities through the federal court.
This is not legal advice but a general comment on society based on a limited set of hypothetical circumstances. No one should act or refrain from acting based on these comments without seeking appropriately licensed legal or professional advice. The author disclaims all liability in respect to actions taken or not taken based on his comments.
Mr. Levy is right about a law suit, but that is an expensive proposition.
You might consider having an attorney write to the offending web site. The host may take more notice from a lawyer than a visitor, and it would only cost you a few hundred and not many thousands like a law suit.

"Harass" and "bully" and "defamation" are legal conclusions. It's impossible to say what your options are without more information, including what was said, who said it, where the individual is located, or if you even know the individual, and what forum it was said on. I recommend you call an attorney in your state to schedule a consultation, and provide copes of the offending posts, so the attorney can give you advice based on all the facts, while being able to ask you questions. Good luck!
To schedule a consultation, call my office at 407-965-5519. I am licensed to practice in Florida only. My answer does not create an attorney-client relationship, nor does it constitute legal advice. Proper legal advice can only be given after learning all circumstances and conducting a comprehensive examination, including being able to ask questions, and cannot be given just from reading one question on an Q&A board such as this.
