hello

i implented a turing check on a friends guestbook. he had several spam
entries a day lately. now a couple hours after i activated this, there's
again a spam-entry in there.

do you think the turing number could be readable by bots? (i changed the
script a bit, the number was barely readable by humans before...)

or are sometimes also humans making those entries? does anybody now the
approximate percentage of humans and bots making theses entries? other tips
how to cope with this?

thanks for your help
