WordPress is really nice when it comes to coping comment spam. You can configure that postings with more than a certain number of links shall be held for moderation. I, the moderator, then can go to the overview of the pending comments, and then decide which comments shall be posted, and which shall be deleted. It even supports a bulk-edit mode, which makes deleting or approving a lot of comments at once really easy.
So, as you can see, I'm still really happy that I switched to WordPress, as it makes so many things so much easier. It's even possible to get it conforming to XHTML 1.0 and CSS without a lot of work.
