Blacklists are not restricted to domains (at least SquidGuard's isn't). Obviously that would be ineffective. SquidGuard's regex matching works great, for one. And their URL blocking is especially effective with blocking sites that continue to register new domains to evade bans (They're not all smart enough to change the directory structure for the phishing/spyware kit they got.) You are right though. We can argue all day about why it is/isn't effective.

But whether blacklists are effective or not is surely hard to decide and more a religion than a science. But considering that in my country alone ~3000 new domains are registered every day and some domains even contain multiple types of content which belongs to different categories I can't imagine how a blacklist claims to be even remotely effective. You should look at the more inventive users in our organisation? Such a black list would be no obstacle. Cheers Christoph -- Never trust a system administrator who wears a tie and suit.
