Dave made a categorical statement that the only thing that can have an 
effect on phishing is filters. I provided that study as a counterpoint 
which does not support his categorical assertion. He then tried to 
assert that something completely irrelevant to email is pertinent to 
prove his point: another one off study which is irrelevant to email. At 
the very least categorical statements in the face of little data are 
ridiculous, and should be ignored.

I beg your pardon. I designed and implemented SSP. If you don't know 
what this is, you are unqualified to tell me what I do or don't 
understand. Take your ad hominems elsewhere.
