Help with a possible scam

[Edcha]

Hello,

Starting almost a month ago, an unknown stranger named David (they're always called David) started sending me money by PayPal on an email of mine which isn't linked to PayPal. What's interesting is he isn't asking for anything in return. His messages include : "A small tribute, Sir", "Let me serve you Sir", "From David on instagram, Master", "I really want to send to you, Master." The amounts have ranged from 5$ to 100$ CAD. He has also sent me emails with messages along the lines of wanting to serve me. The money doesn't interest me as much as wanting to get rid of his stalking and messages. In what way is this a possible scam? And how do I stop this guy?

Any help is appreciated.
