Reporting Centre, not Censor Centre
A more useful role for the IWF would be to act as a clearing house for complaints about dodgy sites. If they'd set themselves up to ask no questions about how someone arrived at a particular link (unless volunteered by the reporter), they could pass stuff on to the police for prosecution without the outrage that ensues whenever they get something badly wrong. Of course, many of us probably aren't even aware of being quietly censored - a good proportion would probably never even try to access a censored link and most of the rest would probably get there by accident. chances are the bad guys easily bypass the censorship anyway, a bit like making gun owernship illegal in the mistaken belief that it would stop criminals from possessing guns.
