Scott,
This is what we are trying to do. We are trying to to keep the offending members under control, depending on the severity, we warn them, and if they strike, they will be banned from these forums. Right now, as you know it hasn't been that easy because offending members keeps finding ways of getting into these forums. Although, the moderators are trying the best to it's best.
But I don't really think the FBI won't really do anything, if I'm not wrong though. I think the FBI is mostly involved in high profile cases, not in copyrights of a code. But there are copyright infringements suits options or a shut down of the website.
