If they reprogram a bot to randomly hit each one, they have a 1 in 4 chance of getting it correct - bearing in mind that each time the actually answer changes position, the odds go up - with 6 images, the odds go up again - I understand it's a system that can be breached with retries, but increasing the number of images does make it slightly harder. I'm working on making this from Flash format, which I hope bots just can't interpret in any way, shape or form.

I'm tired of removing postings from Russian bots trying to sell everything from porn to cheap mortgages. (Who in their right mind would try to obtain a mortgage via a Russian spammer?)

This idea looks great. I just tried to register on this forum and kept getting the CAPTCHA verification wrong. It's amazing that a human can't figure out the letters and numbers, but the Russian bots seem to have no problem with them.

Fingers crossed that this works!

yay it workz on vB 3.6.5 :D

Installed with 6 image verification. Looks great! Thanks, Jason. ;)

I am hopeful this will stop those pesky little Japanese bots from comin' 'round here no more!!! :p


(The image that is a 'football' is actually a 'soccer' ball here in the States, but effective, nonetheless. )

:up:

You're a PRINCE! Thanks for the football image! ;)

It has been so refreshing to not have to eliminate these bot signups from Japan every day. What a godsend this hack is for admins all over. Great job, Jason! Thanks again. Not one has registered once since I installed with the 6-image verification. Simply awesome! :D

I am running 3.6.5 and tried to install hack and I get this error when I click register.
Can you help?

Warning: dir(images/verification/) [function.dir]: failed to open dir: No such file or directory in /register.php(202) : eval()'d code on line 6

The problems lies with the fact your forum directory is in a subforum from the root - check this post
to see how to change it.

Let me know if this works.

I tried what you suggested, but that did not work. I get the same error message. :(
