AGB 2.3.4 + Human verification >> still get spam

hi

I've installed the newest Advanced Guestbook + the Humand verification mod. to prevent users bzw. bots from spamming in my guestbook.
The problem is > i still get some spam. it worked for about 3 weeks now without any spam entries, but since 5 days i get 3-10 spam entries every day.
Is there anything i can do against this bullshit? The Anti Spam mod should be integrated in AGB 2.3.4 by default - or am I wrong?

if it helps > here is my guestbook (german) > http://www.monokellabs.ch/index2.php?section=guestbook

I found this answer from carbonize @ http://www.totalchoicehosting.com/forums/index.php?showtopic=21180&st=0&p=146125&#entry146125
Hmm I would be suprised if the spammers bothered to get your anti bot test question and put it in their script/program. The one thing I alway sask people who say they are getting spam even with the human verification is this, do you have another copy of either Lazarus or Advanced Guestbook on your server that is pointing at the same database as the copy you use on your site?

... ooops, yes I have a backup of an old agbook on my server. but in folder which has never been linked anywhere. but maybe it helps. i delete the old version of the agbook and come back as an angry man again if I still get spam

Glad you found the answer yourself (if indeed it is the answer). there will always be some idiots who will manually enter spam into guestbooks though.
