The latest skirmish in the never-ending civil war over linking to so- called "attack sites" is the one where [[User:Will Beback]] has taken onto himself to purge Wikipedia of all links to the site of notable science fiction editor [[Teresa Nielsen Hayden]], even though they are used as reliable sources for quite a number of diverse things, because in her blog she attacked Beback (she seems to have some issues with Wikipedia in general).
This has in turn spurred a renewed edit-war over whether the anti- attack-site section should even be in the WP:NPA page, and the page is now under protection again as a result.
