Be ruthless about deleting it. If there's spam visible on your site, it 
will attract more spam. It's like graffiti.

Block anything with more than a few links/URLs. It's very rare for a 
commenter to need to post more than (say) 3 links, but spammers all seem 
to try to post at least half a dozen.

Have typo turn off comments after (say) 30 days. Chances are nobody's 
actively watching any discussion or comment older than that, but old 
comments are just as good for spamming.

I have non-AJAX comments turned on, but I haven't had any spam in a 
couple of months.
