I've been using this code for a few weeks now and spammer activity has dropped off almost completely.
It's not 100%, some still get through, but instead of 5-6 spammer registrations per day, I get 2-3 per month.
It also sends you an email to confirm that it's blocked a spammer, (if you enable it).
It checks with stopforumspam.com to verify the ip, and if they are listed, they are redirected to a new page, telling them how to unlist their ip.
The code consists of 2 files, and one line to edit into a page of your choice.
It works on all types of software, including forums, galleries, blogs, portals, and much much more.
Please check all links in the code otherwise it will fail.
