My blog is very low traffic, so it's not that big of a deal, but using disqus allows me to go through and respond with "delete" in the body when I get a spammy message. Takes about 10 seconds and I can do it from my phone.<p>Of course, I always end up missing some, so I tend to go through every few weeks and prune those that I missed. What we really need is gmail-esque spam filtering in disqus.
