Fighting spam in your guestbook
Spam is a serious problem to all guestbook.
ANG 0.7 has build-in anti-spam capabilities.
So here's some tips on optimizing your anti-spam defenses.
Tip 1
Upgrade to ANG 0.7.
ANG 0.7 has several new build-in anti-spam tricks to prevent robots from spamming your guestbook.
Tip 2
Modify the Anti flood time to at least 30 or 60 seconds.
This will help defending against flooding spam robots.
If your guestbook is subject to a high number of spam attacks, it is recommanded to increase the Anti flood time to a minimum of 3600 seconds (one hour).
Tip 3
Enable image verification with the image method.
If GD is installed on your server, choose the Image method. If not choose the Text method.
The Image method is much more efficient then the Text one. But in case you don't have GD installed, a Text method is still better then nothing.
Tip 4
Use the Censored words management system.
If you notice that spam is mostly ads posts including link, you can censore the links.
Per example, censore the word 'www' or 'a href', and replace it with '****'.
To make this censor efficient, enable the Auto censor messages.
This will automaticly unpublish all new posts containing the censored words.
Then you can easly delete the spam posts by clicking on 'Delete all unpublished posts'.
Finally empty the trash.
