Description:

Anti Bot: Captcha Clock v2.2


Compatible With:SMF 1.1.X - SMF 2 Beta & RC1
Created By:Karl Benson
Developed By:.LORD.
Version:2.2
Languages:English
A new and unique Anti-Bot Registration Check. Rather than getting registrants filling in letters, have them tell the time on a clock.

Quote from: Karl Benson
It is a cat and mouse game between forum software and bot-creators to secure forums against spam bots.
Using generic/centralised anti-spam measures makes it viable for bot-creators to try to get past them.
If every forum employs completely different anti-bot measures it makes it almost impossible to create bots for mass-automated registration.

Some people think that this MOD is "ugly".
I have tried to make it more agreeable for humans without decreasing the difficulty for bots.
I deleted effects little or not detrimental for bot, and unpleasant for people.
And I added other effects more annoying to bots and less for humans.

REQUIRED: A manual edit is REQUIRED for ALL themes (other than SMF Core Default) which have a custom Register.template.php
If you don't do perform the edit, nobody will be able to register using those themes.

REQUIRES Minimium:
- PHP >= 4.3.2 & GD Library 2.0.34 (or newer)
- Do NOT install the mod if your server does not meet the minimum requirements.
- To check what GD Library your server has goto Admin > Support & Credits
- If you get an all black image or it doesn't appear correctly, you might have a dodgy version of the library.
Please do NOT ask me how to install GD library or upgrade it.  I don't know.
