I should have seen this coming: comment spam. A bot posts a meaningless comment to your blog and leaves behind a link that points to their porn or e-business site. I got hit by it a few times, though at least (so far) the comments themselves have been dumb but innocuous. In a larger sense, it’s interesting to watch the blog community immune system kick in. The reaction has been vigorous, ranging from informed discussions about various corrective actions to outing the alleged perpetrator (see the continuation here). All the discussion, and the speed with which it matures, makes me confident that we’ll have some good solutions in short order.
I’m always a little concerned about violent reactions because once you’ve made it clear you have a knee-jerk response to something, someone will come along and hack your reflex to bring about their own desires. For instance: people really hate spammers, so all I have to do is convince the world you’re an unrepentent repeat-offending mass spammer and other people will take you down for me. Or as they said during the French Revolution, j’accuse!
