Try these three plugins in combination:
http://wordpress.org/plugins/cookies-for-comments/
http://wordpress.org/plugins/simple-trackback-validation/
http://wordpress.org/plugins/akismet/
I’ve found the combination of these three to be highly effective at stopping spam, without a lot of effort required on your part.

Right now i am fed up with spam comments. I have already tested akismet, grow map anti spambot comment plugin and other plugins but not able to stop spams everyday my blog http://www.binarynote.com receive more than 2500 spam comments so i am right now planning to remove comment system from my site, If i would remove comment_template from my theme then, is it possible for bug to still fill my database table with spam comments.
Thanks
