Mods & Plugins (Releases & Support) / [MOD] Anti-Spam v1.0 for Guestbook & Comments
« on: March 23, 2006, 09:17:12 PM »
[ Introduction ]
This Mod prevents spamming from Bots in your Guestbook and Commnts,
if you allowed guests to post there.
[ Features ]
This Mod works with an security code,
which must be validated when posting.
The security code is submitted using session system and javascript,
so users which have enabled javascript (which usually most users have),
doesn't notice anything.
users that disabled javascript have to enter the security code manually.
This is an great advantage compared to the captcha solution,
where every user have to enter this code, what is very uncomfortable in my opinion.
You can choose yourself if you use this mod only for guestbook/comments or for both.
[ Notes ]
At the moment the security code is on an very low level,
and not encrypted or anything else,
but it should anyway work.
If somebody gets anyway spam, he/she should contact me,
then i will upgrade this mod.
This mod works with 1.71 & 1.72
other versions are untested.

[ Installation ]
