@starshine I am in contact with a group in Kakuma that I support directly. I have regular video chats with my friends there. Conditions for them are very hard, and I'm happy to help them any way I can.
However, this being the world it is, I am absolutely 100% sure that there are other actors out there who are perfectly happy to use their plight as a way to scam people.
For my background, I worked in International Development for many years, alongside my wife. I knew enough to tell a legitimate story from a fake one.
Be careful when dealing with this kind of thing. If you have any doubts and still want to help, give to an organization that works with refugees, such as International Rescue Committee or Medecins Sans Frontiers.
