I have not read that to be honest. I did read and write that accepting such monies should exclude you from giving financial advice. Especially someone from a developed country who has not been able to create his own financial nest egg but wants to tell someone in a third or developing country how to manage their funds.
At age 18 - 25 we aren't all that financial savvy. I can also imagine that boys in this line of work need some tension release and might overspend. It's hard to put myself in their place.
