I've received a kind of e-mail that I can't decide whether to think of as helpful or dangerous. A person—but the style and form of the mail makes me think mb a bot—writes he has found a broken link on my blog. He's chased down a current link to the same resource (an academic paper). The new link is to a page on a rather random server. I wonder whether the plan isn't to point the link elsewhere once I've "fixed" it. (I found a more reliable link, used that rather than the suggested destination.)
