That's not the point! The point is that you didn't report it and you told someone else who had no reason to be notified. While reporting it to the people responsible is not required by law, it is the right thing to do.
Regardless of your intentions, by informing a third party, you facilitated a crime. Also, regardless of where you or the actual perpetrator are located, the server is in the United States. That involves the law enforcement authorities here. Due to the nature of the internet, unless it can be proven that the server and perpetrator are located in the same state, it is an interstate crime and thus involves the FBI.
Get a lawyer dude. A good one.
