[Update 2:] So I switched back to Akismet and forgot to put the API key back in. Comments should be working now.
As you know we’re beta testing the Defensio module for EE and, like any beta test, there’s bound to be some hiccups. Right now the module is marking every comment as spam and moderating it. This isn’t a huge deal as I just mark them as OK and publish them when I get the chance, but it does mean that your comment may not show up immediately after you post it. I’m working with the author to see if we can’t figure out what’s going wrong and get it fixed ASAP, but if it looks like it’ll be awhile then I’ll switch back to Akismet until a new version is ready. Just wanted to give you guys a heads up as to what’s happening with it.
Oh, and for those that have asked, the Defensio module for EE 1.xx will be free when it’s finally released. They’re not sure about whether or not they’ll charge for the EE 2.0 version as it’ll depend on how much work it takes to port it over.
[Update:] I’ve switched back over to Akismet for the time being until a fix can be found.
