Not so doh! - the BlackListPlugin says "To fight Wiki-spam, the Plugin can
also add a rel="nofollow" parameter to external URLs.":

I'll take a look at it.

We could end up with a pretty unmanageable user list, though.  I'd rather do
something to discourage bogus accounts from being created, if we can.

Continuing on my quest for a qualifying question for signing up, how about
providing a Scheme code snippet which people can paste into their favorite
implementation to run it, and then enter the result on the signup page?

I'm thinking of something short & simple but not too obvious, maybe
rearranging a list with car/cdr/cons.

But slightly tongue in cheek, we could provide something like this:

(let ((k (call-with-current-continuation (lambda (k) k)))
      (seeds (list 7 4 3 2 11)))
  (cond
    ((procedure? k) (k (list k 1 car caddr cadddr)))
    ((null? (cddr k)) (cadr k))
    (else ((car k) `(,(car k) ,(* (cadr k) ((caddr k) seeds)) ,@(cdddr
k))))))

;o)
