It's true that they check your visa or RP before checking in, but airline staff can't tell if that visa is real or not. If you can still remember, the visa that you have before your RP is just a piece of paper print out from a computer that anyone can make. That's why every airlines are obligate to fly their passenger back even if they only have oneway ticket when they become IN ADMITSABLE.
But, if they can actually clear immigration then airlines are no longer responsible. Now it became the responsibility of their sponsor (which does not exist) and the Qatar Immigration Department. I don't know how these fake companies obtain those visa, but we can see that more and more labor became homeless people here in Doha.
Most labor that got stranded here in Doha actually have real visa, but no real job. They would probably love to go home, but can't afford it.
The other case would be those run away labor. They actually have a job, but it's not as advertised and bad living condition so they ran away.
