after giving this more thought...
its tricky because, just about anything you put online is public domain. as much as we dont like it, thats just how it is.
there are numerous "youtube'ish" sites that have the same content and videos. for example, you'll find a lot of the same kind of vids on collegehumor, ebaumsword, etc. which goes back to the public domain point. so you cant really stop someone from taking your vids.
it's possible but requires a ton more effort, to steal vids that dont allow people to embed. it may be an inconvenience, but you gotta weigh your options.
but BECAUSE youtube has sponsor programs, it's super annoying for folks who are making money from their vids to have them stolen and placed on other sites because thats a loss of revenue. however, there'sa slight silver lining. everyone goes to youtube first. they just do. dailymotion and all of those other sites, are way at the bottom of the totem pole. youtube will always be the most popular even if ppl go there just to steal a video. by visiting you, they probably made you money. and i'm sure there's some kind of way in the code that won't hurt your revenue although i'm not 100% sure. maybe there is, maybe there isn't.
so contacting google and youtube and asking them "do i lose money if someone steals my videos and places it on another unauthorized site?" is a great question. you can't do anything really about online thieves, sadly.
youtube could sue this site, but i doubt they will because this site poses absolutely ZERO threat on the popularity and revenue of youtube. it's "too big to fail" LOL. so for now, while its annoying, you may have to just grin n bear it. just make sure you know off the top if you get paid regardless of video placement, because if you don't then u know your frustration is really warranted and requires further action.
but also, harrass the crap out of the website/domain owner and hosting company lol
