Today, I upgraded WordPress to version 2.8.3. I upgrade immediately when a new version is available. And these days, I don’t even test this. I really like WordPress as it is one of the most decent, new-technology, web 2.0 driven, extensible blog I’ve ever seen. The upgrade goes automatically. And it works like a charm.
SpamBam uses a random key to determine whether the posted key was the same as the previously generated one. This key was regenerated after posting the comment. I assume that WordPress now calls the do_action(‘comment_form’… not only when generating the page, but while posting the comment as well. And there’s the problem. SpamBam registers the generation of the key in the comment_form action, so the key is regenerated so that it doesn’t match the key on the blog page anymore.
Since I didn’t immediately find a solution for this and since SpamBam isn’t updated since ages, I started to search for another anti-spam plugin that doesn’t work with captcha‘s (extremely annoying and not working after all) and is really reliable… I found WP-SpamFree which seems to use about the same technology as SpamBam, but a little more sophisticated and it was updated only recently. It feels more solid and commenting now works again.
I now enabled a logging feature to see how many spam comments are blocked, just to see whether it is actually working. And ehm… hopefully I don’t end up in receiving spam comments again. But I doubt it. Since its installation, WP-SpamFree blocked 12,250 spam comments already.
