What's the WORST could happen?

Hi, what’s the worst could happen:

  1. If I setup a movie streaming site? Any way to prevent the respective companies to shut me down? Can they track me via my IP or something? How does DMCA Ignored offshore hosting helps in this case?

  2. If I send emails to scraped email lists that are obviously non-opted, will I get in trouble (fines, jail)? I see many people doing this even after the DMCA rule and they seem to be doing just fine? What is the work around for this?

  3. Best payment method for such things above? Don’t want to use paypal.
