Recently, I started using the WP-Hashcash plugin on several blogs and have been pleasantly surprised with the results.
Although I am happy with Akismet, it does occasionally allow automated spam through so Hashcash provides a welcome extra layer between the comment submission form and the Akismet queue.
Essentially, WP-Hashcash uses javascript to check on the client side that comments are submitted via the blog comment form in a browser window. Auto-spam bots use scripted submissions that do not need either the submission forum or the browser window.
The Hashcash settings allow detected spam to be either deleted or shifted to the Akismet queue for processing.
If you are seeing occasional spam make it through Akismet then I certainly recommend giving this plugin a try.
