CAPTCHA - Really need some help
Posted: Tue Jan 31, 2006 10:15 pm
Hey, I'm new here - found the site just surfing the other day and saw a great community of programmers that I wanted to be a part of. Lots to learn from you people. Anyhow, sorry for my first post being one of a problem but it is.
I have been working on CAPTCHA and I just can't seem to block a spammer that is hitting a guestbook that I made. The guestbook is at http://www.groonesworld.com/gbook/index.php?act=add
The spammer is posting things like
"Just wanted to say that the site has really grown from strength to strength."
"I must confuses your site is really cool!!! Great site, great idea, just all round great work, everyone."
"One sentence. The site is awesome. Just great Keep it up and up!!! An excellent website indeed!"
"http://h1.ripway.com/loans/mobile-home-loan.html mobile home loan http://h1.ripway.com/loans/home-loan.html [url=h"
"Nice site! Color scheme no bad... Add spam protect and be happy ! Random code =763"
I end the CAPTCHA image session, I have grids in the image, I have random marks on the image, I have the letters and numbers turning. I use mt_rand and then I run them through md5 with a substr. I am to point of thinking this is an actual person typing this stuff in...
I have tried to capture the real ip but have failed. This guy puts on a message like every hour...I don't want him/her to stop because I want to figure out how to stop him/her. I guess I could store the messages in the db and release as I see fit, sucks to have to do that. I was also thinking maybe a challenge question of some sort.
Anyone got any ideas?
Thanks!
