Akismet sucks. If you leave a comment on someone’s blog and they disagree with your comment, they get you banned from commenting on all blogs by falsely makring what you said as spam.

I, too, receive hundreds of spam attempts per week on my site. As I use my own custom blogging / CMS code, I wasn't able to rely on the standard WP/MT antispam plugins to do the job. Originally, I was keen on the idea of using a hidden field (hidden through CSS visibility). However, I would caution anyone thinking of using it: From what I recall, Google (via Cutts) has indicated a distaste for invisible text (due to its black-hat prevalence). Considering the penalty for triggering a SEO red-flag, I don't think it's use would be prudent. I have created an spam statistics & technique page that might be of interest to those who are trying to build custom detection methods that build upon some of the suggestions you've already written here. In addition to custom filters, I am now running Akismet in parallel to see how it compares. So far, I haven't observed any false positives, but I did encounter a number of false negatives. This is easily explained by the fact that it does not have access to special form field content that provides additional indicators of harvesting and bots.

Nice suggestion. I read that you mention about captcha will trouble the commentator. honestly, it is not. unless the picture of captcha is hard to read. it can cause put mistake word and do it again and again.

about change field name, it is not all user can do it because it need scripting knowledge.

Thanks for the tips. I was trying to figure out ways to get rid of spam as askimet wasn’t doing 100% great.

I used to get hit by heaps of spam until I started using Spam Karma. I've found it very reliable.

Interesting solution, although I’d worry about users with Javascript turned off!

I was doing that myself until a reader e-mailed me complaining about why his comments never get posted!
