Livestreams don't seem to have the same content id system as uploading a video normally does. Right now it's a free for all of people trying to suck up the ad revenue. If you try to upload that type of stuff as a normal video it'll always get blocked, but livestreaming it seems to be working for a lot of people right now. Easy way to get banned, but if you skate long enough you might get a good single payout from adsense. I don't think it's worth getting banned on there, though.
