A plague of "comments"
Here's a question for any fellow bloggers:
Has anyone else seen a huge increase in "comments" over the past few days?
These comments are mostly on older posts and are obviously intended to generate links to for-profit or crackpot websites. Usually there's some superficial reference to the post, enough to convince me the comment was left by a human, but not one with any particular expertise or interest in the topic of the post.
A quick Google search shows that people are selling this "service" for as little as 5 cents per "comment."
I am using Movable Type's "Report Spam" feature with these, hoping that will make it harder for them to spam others. Any other suggestions?
