Jeff Duntemann's Contrapositive Diary Rotating Header Image

December 9th, 2010:


I didn’t get much comment spam the first year or so that the main Contra instance was on WordPress. (The LiveJournal instance is a mirror.) I moderate all comments from new commenters, and now that the daily comment spam rate has crept from three or four up past thirty or forty, I figured it was time to do something.

So yesterday morning I installed Akismet, a server-side comment-spam detection plug-in for WordPress that applies a Bayesian signature scheme to incoming comments, and bins the ones it considers spam. Installing it was effortless, and for personal blogs like mine it’s free. (For commercial entities the Akismet service is $60/year.) So far, in about thirty hours it’s identified 80 spammy comments, which remain in the bin so you can scan for false positives if you want. Everything Akismet has fingered so far has proven to be spam. However, I’ve gotten no genuine comments on my WordPress instance since installing it. If you posted (or tried and failed to post) a comment on my WordPress instance today or yesterday, let me know. If nothing is in fact interfering with legitimate comments, this thing is a godsend, and if I sound a little nervous, it’s only that it feels maybe a little too good to be true!

[UPDATE 12/10:] Well, four comments successfully posted, and nothing spammed that shouldn’t be (or not spammed that should have been) suggests that Akismet is a win and I should stop worrying.
