According to him I owe him 32BTC. This is a false scam accusation, and if he wants to defend himself, kindly post a TxID of the 32BTC transaction.

Can I ask you one thing: why didn't you contact him (privately, through PM) instead to open a thread here? C'mon you (both) are acting like a kid, but I haven't the right to judge you. However the trust system isn't moderated so only him can remove/change the negative trust.
