Broadcaster Derryn Hinch has vowed to continue a campaign to out convicted sex offenders despite being found guilty of breaching court suppression orders.

Hinch, 67, was found guilty of four contempt of court charges and had one charged dismissed by Magistrate Charles Rozencwajg in Melbourne Magistrates' Court this afternoon.

The "human headline" continues to live up to his moniker with the dramatic court proceedings playing out as he battles terminal liver cancer.

Hinch was charged with contempt of court for publicly naming two sex offenders, whose identities were subject to court-imposed supression orders, during a "Name Them and Shame Them" rally in 2008 and on his website.
