Anti-spam, hopefully not anti-user

In what I hope is the only site-admin post I have to do for a while, please let me know if you have any trouble accessing the site, leaving comments, or receiving RSS feeds.

I do realise the irony that you probably won't see this post if you are having trouble, but if you do find this, please email me if you are having trouble (alastair at this domain).

The reason I'm asking is because I've installed another anti-spam plugin (Bad Behaviour), to compliment Akismet.

Akismet has being doing an awesome job, what started as a trickle of 1-5 spam comments per day when I started has turned into a flood, currently at over 700 a day. It's gotten to the point where almost 20% of the activity has an 'unknown' user-agent in my stats, which is pretty annoying!

Therefore I'm trying another plugin that prevents certain robots from accessing the site at all, but obviously there's a possibility that it could prevent people (or Google) from accessing the site.

I'll let you know how it goes, but please do email in if you spot a problem.
