I suggested to use
http://www.phishtank.com data freely as it is community based, open and you can easily fix the things which are wrong very easily. It is backed by OpenDNS
1password came up with same idea and in fact, phishing protection with phishtank happens _right now_ if you use 1password/omniweb integration and enabled phishing protection in 1password prefs.
No cats died as result ;-)
Here is the API, free

Best thing is, WE can help, as users. Several prestigious vendors like Kaspersky keeps them updated with their own data too.
