The reason for not blocking phishing websites within the CleanFeed
system is not that -- but that the design is poorly suited to it!

You'll recall I said earlier:

    I think the main reason that people thought it was complicated task,
    was because it IS a complicated task -- unless of course you merely
    wish to block a relatively small number of sites that are not taking
    active steps to avoid being blocked; and you don't mind that the
    system is trivial for customers to evade.

... and the phishing attackers ARE taking active steps to avoid blocking
and the way in which the sites are accessed does on occasion equate to
evasion by the (unwitting) customers.

It would of course be very convenient for "CleanFeed" and the other
systems to start blocking material which it was lawful to access; it
would then be possible to do some sorely needed research on their
practical effectiveness. Attempting to access child abuse images is
unlawful, which prevents experimentation in this area.
