Possible Scammer!

A few days ago I sold my main we used a MM (MM is now banned) The guy I sold the account to tried to recover the paypal money he sent me. And then sends me a message saying "You recovered the account I'm recovering the money" I explained I didn't recover the account and the only person who knew the info was the MM, so I assumed the mm scammed, so I recovered the account and offered to give it back if he cancelled the paypal dispute, he wouldn't cancel the dispute and it was settled by paypal in my favor. He has now posted on sythe saying I'm a scammer
He keeps pming me demanding the money back, sounds like he is in-fact the scammer.

Any thoughts?

I sold my account to Brawl Boy
