There is a good article by Christina Sterbenz for Business Insider titled, "Are streaming sites legal?" You can look for it by title or by going to www.businessinsider.com.
The article not only explains nicely how streaming sites work, it also provides information on how to recognize legal sites and what you can and cannot do with the copyrighted material you run across online.
I agree with both Silverplum and Zigner that you should be applauded for looking into the legalities of streaming content before streaming what could be infringing material. Many posters come to this site only after they have been notified that they have infringed - at which point their options can be limited and generally require payment to copyright holders to compensate the rights-holders.
Went to the linked site and searched the author, found nothing on the first many pages. When I search for the title, I might choose a different thing to search for. Perhaps something like, "How Sketchy Streaming Sites Really Work � And Why Some Are Legal". While the information is something that might be safe, the reason it is safe is not because it is right, but because it is from someone who WANTS that to be the law. quincy seems to be on the side of those who claim rights. He is mostly correct on the legal authorities. I have left this place at least once because he propounds the nonsense of the current theory of IP. It is stupid. The penalties are too great and the reason for the law seems to be subjugated because of money. Like most things, everything you do is illegal. We all violate IP law many times a day. As I have said, and has not been challenged, simply visiting a site that has a non-licensed content is a violation of the law. A violation that could cost thousands. A violation that could be a felony. "Copying" your data to the RAM has been determined by appellate level courts to be a copy. If you do not have the intellectual rights for such a copy, you are by case law and technically, in violation that is a felony and has substantial statutory damages. Sure, "prosecutorial discretion" saves us all. Even though if you piss off a prosecutor you have big, big problems; most don't have to worry. I mean really, who needs to worry if the powers that be decides in this instance all of us have done is not a violation?
Just thinking about this angers me and is a part of the weakness of the forum. I think I will leave for a bit and allow the bias to come in for my claims.
But, we are all felons under the way the law will be described.
Vote for people not in the thrall of the content holders.
"It's too complicated for most people," should not be a felony or a tort that can ruin one's life.
