I use some apps and sites to practice speaking English. I have received an email from a certain staff on another apo quite a while ago. He said "Pleas be careful a man who I have talked before, he demanded money to another woman. " I wasn't sure whi he was. I usually delete people who has never sent me audio messages and just said "hello" or "hi".
Recently I forgot sbout it, but I watched a news about scam for Japanese senior woman on apps which I have never used. The suspect used a profile picture of an another man to pretend. I am not sure my experience has something to do with this criminal, but the victory paid 12 milion yen for her love. She has serious disease, so he always tried encourage her for money.
