You probably don’t know, but I’m working with some other Fedora contributors on a Fedora install of WordPress MU. The thing is, for a spam solution, all of it has to be open source, so Akismet or reCAPTCHA won’t work. So I ask you, Fedora users and contributors. Firstly, is spam an issue on your blogs? If so, what do you use for anti-spam on your self-hosted WordPress blog? Leave a nice little comment.
