Banned after (first) long message, probably Spam-triggered

Hi,
I did my homework, googled and searched and tested a lot.
In short: when typing a short message, it gets added without any problem, however, when typing the first, real, long message, I get banned. (guestbook still in test-phase, not launched yet)
Since it works with short messages, and I get banned (because of Spam) while typing a long message, I guess there are some words triggering falsely. Can anyone look into this? Does this occur since the message is in dutch while badwords file is english?
Here's the message:

Ik hoop dat je je dromen waar kan maken en dat je zaak een geweldig succes zal worden. Net zoals jij zo stralend bent, maak je de prachtigste foto's. Je bent echt uniek en iedereen die jou inhuurt haalt zich de beste in huis die er is.
Heel veel succes!
-x-

Thanks a lot!

Hi,

I checked the text and GBook wrongly recognizes "worden. Net" as an URL address and hence bans the message. As a temporary solution try reordering the words a bit so that "net" (or "com" or "org", ...) doesn't stand behind a dot "."

Thanks for your effort. Hope the guests won't have this problem often...
