He is a scammer from Egypt, he is a global scammer.

There is a strange number calling me; he is a professional scammer. He says and sends me messages on WhatsApp saying that I am poor and need money. He asks if I can send him 500 dollars. I asked why, and he said I need it. I said no, I don't give money to anyone. He told me I could be threatened. I asked him why he would threaten me since I am American.
