Unfortunately, no. To pursue a lawsuit there are two different things needed. The first one is damages, but it is often easy to find some kind of damages. The other one is a "cause of action" and that's where the issue comes with this case, there is no cause of action. There is no specific law against online bullying in a case like this but not only that, the website owner is protected by the Communications Decency Act. You can read about it at http://en.wikipedia.org/wiki/Section_230_of_the_Communications_Decency_Act.
This is a wikipedia article that provides some background on the Act.
Essentially, the CDA states that when a user of a website writes and posts material on an "interactive website" like those with forums, games, etc. the site itself and the owners cannot, in most cases, be held responsible for the posted material. Specifically, 47 U.S.C. § 230(c)(1) states, "No provider or user of an interactive computer service shall be treated as the publisher or speaker of any information provided by another information content provider."
In addition, the CDA allows the website or its owners to countersue for attorney's fees and costs if they are sued.
If your question has been answered then I'd offer my best wishes to you and ask that you please not forget to leave a Positive Rating so I receive credit for my work. I am truly sorry to give you what I am sure is bad news, but please understand that it would be unfair to you (and very unprofessional of me) to provide you with anything less than a completely honest response. However, if your concerns were not satisfactorily addressed, then please let me know, and I will be happy to clarify my answer. Please remember to rate me based upon whether I answered your question, and not upon whether the answer was good news or bad news since I have no control over whether the law is in your favor or not.
Of course, please feel free to ask any follow up questions in this thread. I want to be sure that all of your questions are answered. In addition, once you issue your Positive Rating the question will lock open and you can come back to it anytime in the future if you think of something else.
