I am looking for a solution to prevent spam bots on my contact form. I used to use recaptcha but had an umber of complaints from mobile uses who basically found it impossible to use recaptcha on a mobile with JS turned off.
Instead I have been testing the PhpCaptcha module on here although this is not working by always returning a wrong captcha. Also this sometimes only generates 4 characters, which may be the cause to this.
Is there any other solution?
