For those who are following along - Opera uses two sources for their anit-fraud, or phishing, blacklist - and a third source for their malware blacklist.

Opera sends the domain name of the requested page to the server, which checks it against phishing blacklists compiled by Netcraft [netcraft.com] and PhishTank [phishtank.com], and malware blacklists compiled by Haute Secure [hautesecure.com]. [opera.com...]

Anyone with a false positive in Opera for either phishing or malware needs to work with these third parties to get the status changed. The information for how to do that is available from those three websites.
