Don't know about you but I've never managed to filter spam on a site
reliably with _only_ baysian stats (+ usual rules on so many external
links etc.) If not using an external service - which as Ringo points out
elsewhere isn't an option for Indymedia because it leaks information to
third party sites I've always required some additional captcha. How
inaccessible these captchas are depends... one of the present favourites
just includes a visibly hidden field you are told not to fill in - but
bots tend to anyway.

Cheers,
