Question

A charity organization from a neighborhood of kollel families in Jerusalem, which supports a great deal of Torah study, circulated an option to pay some seminary 220 NIS, and they register whoever pays as a student. In return, the payer can get a student card and pay very little, if anything at all, on the state's public transportation.
Somebody remarked to them that this is exploitation, a scheme, and not honest.
 
They answered that everything is legal.
 
I saw the registration form for that seminary, and it has details there like name, email address, payment method, etc., and there is no mention whatsoever of their studies. The person registering is presumably entitled—I'm assuming that if I dig around somewhere I'll find some kind of course that can be accessed online from them or something like that—but on the form itself it only shows name, email, payment method, and so on.
 
Is it proper to keep away from this kind of scheme?
