Pretty much once a week or so, someone in my aggregator complains that they got a ton of comment spam. For some reason these people are not yet running MT-Blacklist.
This is most definitely the easiest and best way to keep comment spam off your blog. I got killed a few times and finally spent the time to install it and LOVE having it every minute. I still get comment spam from time to time, but with just one click, it goes away and the URL is added to the blacklist.
So, people, stop complaining and just install this software.
