Has anyone been able to successfully prevent spam on their site without placing a burden on your visitor (e.g. CAPTCHA) and without using a centralized spam reporting system (e.g. Akismet)
I've found this & it looks promising, but doesn't contain detailed deployment instructions.
I want to present my web forms without burdening my users with CAPTCHA like technologies, but also actively automate preventing spam.
There doesn't seem to exist a detailed instruction/tutorial on how to implement such a technology.
Disclaimer
Also, I realize there no silver bullet appropriate to preventing spam. But if simply putting in place a non-invasive (invisible to user) prevention system that blocks 95+ % of spam, it would be worth the effort to deploy.
