- Fix our captcha generator. I'm not terribly interested in this, I
think it'd be a lot of ongoing work (particularly in a clustered

- Implement a super-simple 'captcha' with a string, which I've done
for the blacklist removal form. i don't see a lot of evidence of bots
trying to break our captcha, I think this is sufficient for our needs, I'll
get started unless someone has a compelling reason to fall back to (2).—
