Last month, Adayfi was cut off without explanation from the money transfer service Western Union. He had been using the service to send small amounts of money home to his family in Yemen to help pay for his mother"s monthly medical expenses, he said, as well as receive donations or payments for work from abroad. Citing company policy, Western Union said it could not disclose to Adayfi or the BBC why he was cut off. A spokesman said the company "takes its regulatory and compliance responsibilities very seriously", and had reached out to Adayfi about his case.
