Review:
Basically, these all seem to be the exact same web file just with a different image, some altered text, sometimes a little change to the js. You'll have to add a new-tab redirection to your survey or add the popup to appear on that page to unlock and then to enter in the required code to "unlock" said surprise or generated item promised.
For one say, Facebook, it does seem to fetch the names and detect incorrect entries so the code inside of these can be used for your own skinned website, or you can simply alter what is already in here.
You'll definitely need to find new images as they are already branded with the original creator but that is no more than an hour of your own time.
Overall, it's a bunch of good niches and a decent starter pack. If you're going to use this, my advice is that you do, and I mean do, rework the code to make it unique to yourself.
Other than that, you can essentially buy a domain that may fit all of these, load them up and then provide links and a redirection to them.
So, once again. If you're starting out, this is a pretty decent starter pack, get it while OP wants to bother with releasing. :P
