I’m getting a steady stream of blogspam directed at my blog: around 100 hits a day. The combination of comment moderation and spam filtering means that none of it has got through to pollute the site, but checking for false positives is getting a little tedious. One change I’ve just made is to automatically disable comments on each entry 21 days after I post it. This is unfortunate: some of the most amusing comments have been from people who discovered one of my postings months or years after the event, but c’est la vie.
