WordPress bloggers should beware of spam right now: Akismet, the integrated spam-catcher, appears to be down, or at least is showing “API Key invalid”. The spammers are running rampant. I would be very reluctant to have barriers to commenting, such as moderation or catchpas, so have just installed the very latest versions of Spam Karma 2, and Bad Behaviour. Also been thinking up a long list of dirty words to ban outright over at our kids’ site, Storynory.
P.S. Instead of reinstalling Akismet, I’ve added this plugin within a plugin to Spam Karma 2. SK2 checks comments against Akismet’s blacklist of bad commenters, giving you the best of these two plugins.
