XF 1.5 How to add custom human verification question to registration?

[Forumer]

Hello,

I've Googled and searched the forum but cannot find information about how to add a custom question to the registration process in order to thwart spammers, e.g. "What was the name of the narrator's alter ego in Fight Club"? Can anyone tell me how this can be achieved?

Thanks!
