Yesterday I blocked Fys for edit warring and serial reversion in respect of text sourced from an attack blog in the article on Anne Milton, a British Conservative MP. We know from other evidence that Fys is an active member of the Labour party; this may or may not be considered relevant.
The content was actually jointly sourced to the attack blog and to an article in the press. Another editor has modified the content to be sourced solely from the press article.
Fys is now agitating for the blog itself to be linked. I don't think it's appropriate. It is probably acceptable in the article on its author, Tim Ireland, but I don't see how it comes under any of the acceptable reasons for linking to a blog, especially in a WP:LIVING article.
Fys being Fys, this is not going to go away until he gets his way or some escalation takes place. I'd like to know whether it's worth the effort - in other words, is it OK to link an attack blog if it is mentioned elsewhere, albeit as a bit of local colour in the election coverage? I note that the blog is not linked from the Times article from which the text is sourced.
