Comment Spam

By Deane Barker on February 10, 2006

If it’s not obvious by now, I’ve tightened up the spam filtering. We’re getting hammered by comment spam this last week or so — some big new round of scripts is going off.

I’m sorry if your comment is delayed, but it’s either that or TypeKey, which I don’t really want to do either. This sucks. I have to find a solution of some kind — I’m open to suggestions.



  1. A popular spam protection mechanism I’ve seen on many sites is the use of security graphics. Along with the comment box, users must enter letters/numbers they see on a graphic. The characters might be in a unique font or rotated so that scripts cannot recognize them, but still readable by site users.

    I wonder if there’s an online service that help websites verify human input… :-) I’ve seen it on Yahoo (probably home-brewed) and also on updated PHPBBs.

  2. Caveat: I’m not familiar /at all/ with running blogs or defending against spam attacks but I remembered your spam entry when I happened across OpenID, ( From the website:

    “This is a decentralized identity system, but one that’s actually decentralized and doesn’t entirely crumble if one company turns evil or goes out of business. An OpenID identity is just a URL. “

    I’d followed a link to from website of a company that offers an implementation of OpenID called libopkele ( How did I get there? Why, via the source of all things good(tm): the newsgroup alt.comp.freeware.

    But, as I stated above, I don’t know much about nothing when it comes to blogs.

    best, Craig
