Seeing the screenshot of the headlines, "mimic" (HN title) is a different to "posing as" (article title). If I can extrapolate from 3 headlines screenshot there, the sites have generic boring looks (maybe they're Wordpress sites), but they pose to be a news site for Sevilla, Rome, or Milan. Whereas when "mimicking", I would expect them to be copying the design of well-known news sites (I've seen fake CNN-looking sites).

It's always amusing/depressing when people claim something, usually something fake-news-ey or propaganda) and link to one of these random Wordpress-looking sites as their "news source". I remember someone linking to a page that claimed that a map of the March 2011 Japanese tsunami effects measured throughout the Pacific[1] was a map of the radiation from the nuclear accident, so people do fall for it, because not everyone is as discerning as us super-clever HN readers. ;)
