The "Your family" part needs to be emphasized. These street shitters are proud of the scammers. Their families are proud to have street shitter scammers screwing over the elderly and the tech-illiterate. They love scamming people, it's no different than the street hawkers who sell shitty products. They will literally laugh at you for expecting them to have a sense of shame or expecting their family to disapprove.
