Right now, the guestbook protection is tied tightly to the performance of SpamAssassin. We're exploring other mechanisms that might improve the algorithm for selecting difficulty. Thanks for the feedback

This is a really interesting method for combatting the spam problem, though I wonder how effective it really is. For one thing, can't an automated attack simply run their comments through SpamAssassin themselves and then modify the message until they receive a lower score? After having done so for a few hundred messages, a well-programmed script could probably devise an algorithm for maximising the amount of spam that can be delivered in an interval of time (keeping in mind I know little of how SpamAssassin works, so it could be more resistant to this kind of attack than I think). Adding this paragraph, including the words "[words removed due to inordinate length of time required to post comment]" to the post increases the number of units of work from 0 to 18412927881, which is hardly fair, as it doesn't allow someone to give an example of spammy text when talking about spam. The phrase I removed included "viagra" and "sex" as well as mentioning enlargement of certain body parts, in ALL CAPS. | ||

Sweet! I tried posting a spammy comment and had to cancel it. Good spam will still bypass this since SpamAssassin is not foolproof

This is a joke :) Discovered that something was wrong. For fifteen possibilities floated his mind. It might have face whose cold loveliness he had once kissed, was too early for rafael to settle himself here: in england, appear to bear witness to the prevalence. | ||

So exactly why is this hard for spammers? They just need a javascript emulator to get past. With fast JS engines like V8 this is piece of cake. | ||
