[spam: security hole in my guestbook]

hi guys!! i have a problem but i can't solve it! i have a guestbook on my site with security code validation and an ip-blocker. since last week i have a lot of spam in my guestbook.

description (security procedure):

1. before you can submit your entry you have to enter the security code
2. if you have posted already (within 5 minutes) you can't submit a second entry

description (security hole):

the guy or bot posted 5 entries at the same time (e. g. all post were made at 12:24 with the same ip-address)


how can i close the hole?

if somebody wants to know my site or my code... don't hesitate to...
