Spam, glorious spam

Hello, i read your blog occasionally and i own a similar one and i was just wondering if you get a lot of spam remarks? If so how do you prevent it, any plugin or anything you can recommend? I get so much lately it's driving me insane so any assistance is very much appreciated.

Cory Doctorow received a spam comment gone awry, one that contained 100+ generic spam comments (a spam menu, as it were, from which the spammer was to choose). That’s one of the comments above.

Here’s a comment that Doctorow didn’t get, aimed at education-related content. This comment has appeared online at least 395 times (thank you, Google) and has been deleted, no doubt, many more times. Exactly as typed:

I have been a student at one of the High Speed Universities online since August 2009 and it has been an answer to my prayers. Their assessments and papers are NO easy task, so for those who say online schools are "dummed down" are highly mistaken.
