Topic: CAPTCHA alternative mod that asks simple questions?
I tried to find one, but maybe I didn't look hard enough.
I was seeking a simple 'front-door' anti-spam mod that would add into the punBB user registration form a feature I've seen around the place on other forums, and some blogs too.
This feature presents as a simple text only form element that asks the user a simple question.
Ones I've seen include:
'Are you human?' Yes|No, with no as the default, asked one phpPP forum or
'What does 2+2' = ?, or
'My name is Joe Smith. What are my initials?'
Are there any views on how effective this approach is?
And is there perhaps a punmod that implements something akin to this?
It's certainly not likely to be foolproof, of course. But it's simplicity : probable effectiveness ratio appeals to me, as opposed to a graphic CAPTCHA, Akismet plugins etc.
If there's no pre-existing mod, how hard would it be to just directly code such a question into register.php, manually changing the values from time to time?
