Is international award payment center a scam?

If you put international award payment center into google, all the top hits are from sites with names like "scambook.com", "ripoffreport.com", and "scamnet.wa.gov.au".

I've actually heard that a lot of internet scams are intentionally designed to be SO OBVIOUSLY FRAUDULENT that the only people who could possibly be taken in by them are the small, self-selected, minority of the most gullible people on the planet.

I mean, if you're a scammer, do you want to waste your time with someone who's going to get suspicious and back out after you've been "working" them a while, or do you want to get someone with the IQ of a rock who will happily believe ten times in a row that as soon as they give you just one more unforeseen "transfer fee" their lottery winnings will be on their way?

And, let's face it, anyone who seriously believes that they've won a lottery they've never heard of and don't remember entering, or that Ms. Kwambe Mboto of Africa found 300 million dollars in a refugee camp and that their name was the first one to come to her mind to help her transfer that money to the US, is ... let's just say not the most analytical of thinkers.
