Sure enough, somebody had broken through.
In less than an hour's time, the poster had added more than 30 comments to Disqus, all on different blog posts, all very old -- a clear example of a blog comment spammer on autopilot.

And like any good spam these days, its message made very little sense, with a note to "make money" and dozens of lines in Farsi (or Arabic, I'm not an expert).
The good news is that Disqus gives me a way to delete the garbage. Usually, the service will alert me that a comment is flagged as spam, giving me the option to e-mail my desire to "delete" or "approve" the note, but this gibberish made it through the filter entirely. So I had to go to my Disqus dashboard, and delete each entry one by one. There was no way to delete the whole group or delete all by a specific author, as far as I am aware.
I know Wordpress bloggers swear by Aksimet and other solutions. Some even eagerly trumpet the thousands of spam messages blocked. So far, I've never had the need. Are you seeing spam commenting pick up, and if you're using Disqus, how do you handle it?
