I am not sure if I should be asking this in these forums, but I am going to do it anyway.

I am a 16 year old boy who has overheard my mum speaking to some guy on the phone. I heard her talking about paying for this "signature" and to send the money over so that some people could forge this signature so that he could then send some money over, she has been talking to him for some months now. Recently I found 2 £100 steam codes gift cards and the codes were scratched out (I assume it was sent to him) I asked her about it and she said it was for her friend who was a doctor and he lived in Africa so he wasn't able to get steam cards where he is.

I am just extremely worried because I don't want her to be scammed, could anyone help me out. I know what I said was very vague but that's all the information I have.
