Regarding the hidden form input, make sure you aren't blocking screen reader users/the visually disabled accidently. Make sure you can't end up in that input with the tab key. I've found that comments submitted in less than 7 seconds from page load are spam. On a few low traffic sites I just discard anything faster than that. A few bots seem to load a page, wait a while, then come back to it. But by and large they seem to try to submit the comment immediately after page load. Mind you, this was on low-traffic sites. High traffic sites I'm sure see more varied techniques.
