I have, over a period of time, received several LINE posts from strangers, always with a photo of a young woman, saying they have found me by phone number. Only two people in Thailand, other than my wife, have my phone number, both male. So how is this possible? Some accompanying messages ask if I am still a tour guide or own a restaurant. I block them, but how can people find me by my phone number when it isn't available except to a few?
