    I've finally taken the time to update my spam protection plugin for Wordpress, the original plugin worked well and stopped pretty much any automated spam. But I decided to update it because a few users were reporting problems on this site and other sites, for some reason it didn't work with IE7. Rather than just fix it....

    The latest plugin uses my PHP/JS randomisation techniques to create a key and protect against spam. I've took this bold move to see what affect it has and if the blog spammers will get round it because it no longer uses javascript cookies. My post on Javascript/PHP randomisation can be found here (with source code) the Wordpress plugin can be found on the Wordpress site.
