It costs 0.1 cent ($0.001) to have a human solve a reCAPTCHA.

For forum.dlang.org and wiki.dlang.org I created DCaptcha, which 
asks a D programming question: 
https://github.com/CyberShadow/dcaptcha

It is only activated if Akismet or other spam detectors report 
"spam". It used to have many questions of various difficulty, but 
currently it only asks 1 type of question. So far this blocked 
100% of spam.

AFAIK vibe.d forum uses a Bayesian filter which IIRC generally 
works well but had to be tweaked once or twice. This could work 
well for DPaste if it's trained to distinguish D code from 
not-code.
