Still Getting WordPress Comments while Using Disqus?

After I started using Disqus for comments on another web site, I was still getting huge amounts of spam. None of it showed on the web site, which is good, but it was getting to be a sizable portion of the database.

After seeing several responses to different problems that produced similar keywords, I found this post: How to stop WordPress comment spam when using Disqus. It provides two solutions, one kind of a hack, and one elegant, but both perfectly workable.

I actually prefer the hack, as I believe it uses less processing time.
