Based on this guy's previous posting history, he seems to be trying to seel some mac books. Now, I am not saying he's shady or anything but this trying to sell macbooks for cheap thing is a bit old text book scamming tactic. They get you to list their product on your ebay account or any online marketplace, make you transfer the money to them, and then never ship the item. Which wouldn't have existed in the first place.

The user managed to scam an Indian already. But did not get why did he need recording of notes or may be as you said, he's trying to pull a new scam and needed the recording to prove he has such notes which he wants to sell.
