Kalim, it is the same situation in others countries.(except North America)
In Asia for exemple (Vietnam, China...), you would pay money to fly or even to upgrade from F/O to Captain.
Just yesterday, I received a resume and letter (actually it's not the first time that I read such propositions ),
a guy wrote that he does not have money to pay the LT however he is ready to fly without income in exchange for a few months or so according to the amount of the LT.
He is not even interesting for us since we still have others pilots willing to pay.
I do not really approve the P2F but as I notice from there now, pilots are their own ennemies after all...so... when you read cover letters, your first face would be then and when you get used to it :
