Why Not Kill The Troll?

Mr. McGehee asks:

Why is Anonymoron still allowed to crap all over this blog?

At least two reasons. First, the trivial one. Because in his cowardice (and viciousness), he not only uses no name, but also changes his IP more often than he changes his underwear, there’s no obvious easy way to block him. I could delete his posts after the fact (and I suppose if I did that for long enough, he might eventually get discouraged and go away, but I’m afraid that the creature would just retaliate by spamming me or something when I was away from the computer). But there’s no way to preempt them that I’ve figured out, short of shutting down comments completely, a cure that I think (at least for now) worse than the disease.

Additionally, it would set a precedent. Though I’ve threatened to do it in the past in a couple cases, I’ve never banned anyone here. In general, there’s been no need, because usually the trolls get bored and go on to harass someone else. Anonymous Moron, unfortunately, seems to be quite persistent. I continue to hope that he is just a little more persistent than most, and will not become a permanent featurebug of this community. Unfortunately, he’s too stupid to realize that he convinces no one of anything except that he’s an idiot (I suspect that many people who might agree with him on the issues are tired of him as well, because he’s a caricature of their side, and makes it difficult for them to argue their own points, even when legitimate–I’d in fact be interested in feedback from that community on the subject).

However, I am getting more than a little tired of it myself (particularly since I’m generally on the receiving end of his vile attacks). If anyone has any ideas as to what to do about it, I’m receptive to hearing them.
