As a temporary measure (until some other setting is implemented/activated), account creation could be disabled.
A more permanent measure could an extra captcha added to the registration form (a brief google suggests it might be possible to get media-wiki to do this without too much trouble, and so could be simpler than Vladimir’s solution, which is better), which asks a LW-specific question, possibly randomised out of a list of several, such as:
What is the first (or last) name of the user with the most karma overall? (or, in the last 30 days, but implementing this might be just as hard/harder than Vladimir’s solution)
What is the name of the long series of posts by Eliezer?
What is the name of the sister site of LessWrong?
What is the nth word of the tagline of LessWrong? (where n is random)
(Obviously, a spammer could put special cases in for each question, but with enough questions, or some randomisation, this could be mitigated)
