Enter DCaptcha, a question-answer challenge tailored for D programmers. Its goals are to challenge posters of suspicious-looking content with questions that should be easy to answer to D programmers, and impossible for non-technical people with no incentive to learn or research stuff (i.e. spammers). DCaptcha is already in use on the D wiki (wiki.dlang.org), with great success - DCaptcha's debut cut the short-lived explosion in wiki spam to zero.
I think this is a bad idea because developers new to the language will be turned away. Also i think a lot of these 'easy' questions are just too hard. I've tried the demo and found it fustrating that i need a few trys to get them right.
