We have had captchas installed before and spam bots are still getting through, this is unacceptable. If you have a captcha that prevents anything other than human entries getting through, you've got the job!
We will not pay until we are convinced that the Captcha is bullet proof, so please do not waste your time if you are not sure about the Captcha you plan to install!

Greetings! I'm Kishan. I've developed a captcha script that produces images that are very clear to the user but very difficult for spam bots. Please check PMB for more details...Regards, Kishan.
Captcha is never bullet-proof, it's just one tool of many to prevent spammers from getting though. Tough to say how they are getting through without a look at the actual code, but I'm willing to help.
Hi, I'm very much interested in this work. I'd post the my captcha work which i done to your PMB. Awaiting for the response to start the work immediately. Regards, Senthil.
