My co-worker received messages from a friends dead mother

A co-worker of mine received messages from a woman who died nearly 2 years ago. He was sitting in my office during break and it angered him that someone would create an account of his friend's mother, a woman who died almost 2 years ago. He even mentioned it in his replies and was obviously not too happy. He forwarded me screen shots of his conversation, which I have edited below. All content is of his writing and I got to say, I am pretty impressed with his come backs.

NOTE: I told him to type "Ogun wan kill you" if he wanted the person pretending to be his friends dead mom to stop talking to him. My co-worker added to my suggestion and I am impressed. 

Mods Please delete if this is frowned upon... this is the only way I can share this as I am not the one who did the scambaiting but a co-worker of mine, who only sent me screen shots of the conversation.
