:I've had a look at Talk:Lurgan and, to be honest, I don't think you have a case.  Yes, the timing suggests that he came upon the Lurgan article via your contributions page, but the edit itself looks like a good faith edit and the discussion on the talk page is fairly typical of the editor and his worldview.  It doesn't seem to me either that the edit would adversely affect your GA nomination, whether or not you personally agree with the edit.  In short, one instance, and especially where the editor follows BRD, can't really be called hounding.  The trouble with "taking it further" is that, if you can't show obvious disruption, it may be you that ends up being branded as disruptive.  I would take Angus's advice, and let it go.
