As banal as this question sounds, I am really interested in hearing opinions. These are not mere teenagers pirating movies -- they run massive operations (sites receiving 20 million+ hits a day).

I know of a few teenagers who do this. Their sites have been taken down multiple times, but they never seem to stop. I completely understand that internet forums are no place for seeking legal advice, but I would like to know what can I do to thwart/report these people (in the United States).

(My real concern is that the money they are generating is being used to fund illegal activities in the neighborhood -- which I can not tolerate. I have lost a close one to a drug crisis already, cannot take it more).
