stall recovery

This is not a thread discussing the morality of pay to fly.

How do major airlines around the world view pay to fly pilots ?
Do airlines frown upon pilots who have ever paid to fly in their career ?
How would an airline even know if the flight hours in question were obtained through pay to fly (if the pay to fly scheme ends with a job) ?

Does anyone have any direct or indirect experience with eagle jet international ? specifically, their line training programs that offer guaranteed employment once you complete the training.
Is it just a scam or do you actually end up with a job at the end ?

Thanks for your help everyone.
