The places that get penalized, for the most part will get back up on Google simply by changing their tactic. Backlinks are always important, and they will probably just build more backlinks.

My personal favorite is streaming from my own media server..
I think you are right, I'm guessing that streaming means netflix, or something else. I used to do my streaming on ninjavideo, but they went down, and then came back up with a not as good as before service. Your streaming isn't exactly streaming, the poll probably refers to the first initial source where you obtained the video from. That would be what you should vote for to keep the poll as accurate as possible. not that it is intended to be accurate anyways...
