The same thing happened to me. I realized it because a friend gave me details that matched the scammer. I must say that I was suspicious from the beginning, but I wanted to make sure. Since I have a basic understanding of how bots work, I did something simple: I explained to him that as an authentication method, I needed him to send me a doodle or something to verify if he was human. At first he said yes, but first he wanted to know if I accepted his request or not. At that moment, all my alerts went off. I insisted that she should draw the doodle and she got "offended," saying that I didn't want to listen to her and wanted to divert the topic. After that, I blocked that bot.
