I run Xoops 2.0.13.2 and the last weeks i receive a lot of spam through my guestbook. I post a question about this on the dutch support site and it seems that there are a new kind of scripts that posts the information by itself. The ip number is each time different!

Now my question can protector protect my site for this kinds of attacks and is it compatible with xoops 2.0.13.2?

Thanks
Sorry, for my bad english
