I can appreciate the fact that they are naive or scared if new environment etc etc..helping someone is not an issue but when their close relatives who are closer to where these ppl need to be are not keeping them, then there is a reason and I dont want to inherit bad situations, sorry.
just like there are people who are needy, scared of environment or naive, there are those who are not needy, very aware of what they are doing and very chalak, users I will call them.
and thats for ppl coming for exams, what about people touring US and want to stay with someone? I dont know you, why should i have you stay with me?
