Fedora considering mailing list moderation

If only other distributions would be so aggressive about keeping their community communications kind and fun. Gentoo's lack of a "be excellent to each other" policy on their development mailing lists has driven many good skilled folks away, and stopped new folks from joining their effort. Really strange, as they have successfully fostered a respectful and good willed community spirit on their user forums and in the Gentoo user IRC channels by enforcing a general rule of showing mutual respect. Perhaps others will be influenced by this should it work well for Fedora.
