The bottom line is this is a bad way to implement phishing protection.
Your example proves a very valid point. Phorm would have to look at all ports and look at the protocol being used (http) and then decide if its a phishing attack. Othewise, as your example shows, it would be so easy to circumvent the phorm anti-phishing "service", even for http attacks, let alone https.
