For a while now we´ve been meaning to do this, the code base for the website was as old as the site itself, and for the last few weeks we have been working in a way to prevent the spambots, eventually realising it was easier to rewrite certain parts and upgrade them than to do a "botch job".
These changes are now live and it would be foolish to expect everything working 100% so if you find any problems please report them in the forum post dedicated to this article.
