Well, the way I see it...
<rant>
Keeping something a secret will not protect anybody. And this is just
too easy for anybody to do. The only difference is, if they are smart
enough to avoid getting caught. And the smart ones probably know this in
the first place. I think beating some decency into people, instead of
keeping secrets is far better.
About security and phishing. Banks and others who require tight security
really needs to do other "things" as I hinted. If they dont, then they
are a joke. In general if people got over this sense of false security
and where more alert, and service providers took it more seriously, then
phishing would be dead.
Secrecy has never ever been a substitute for security.
</rant>
Dont get me wrong though, like you, I am also worried about people being
scammed, but I just think that in the long run this is better.
