Exactly how many people are getting 25%?
Exactly none.
If your "application" is accepted does all teh money go into your account?
No. There is no money (except for what you send in).
What about the other people who send their money?
They were scammed.
What happens if after you send the money and if your application is refused?
The application process is just pretend. They may pretend to refuse the application. It doesn't really matter. No matter what happens, more and more money must be sent in order to pay for more applications, bribes, etc.
However, it is nice to see the scammers getting a little bit of a headache. Nos is wasting their time and frustrating them. If everyone did this, the scam would be more work than it is worth, and it might go away. He is actually performing a public service.
