So I contacted one of the more reputable publications that had spread the story, The Independent, and pointed this out. The response from the author was basically that he didn't see the problem and it was up to readers to figure out if it was fake news: "The website quoted in the article does to me look to have a Spanish presence, although it looks like the rest of the news is aggregated. I don't believe there is any reason to disbelieve this particular article, and we have clearly attributed the quotes and included a link to Global247news, so our readers can always make up their own minds."
(For context, the "Spanish presence" was literally an address on the About page for an unnamed "Webmaster" which I'm not sure even exists as an actual address in Spain... and in itself seems a little fishy, given that the website was very definitely not registered to someone in Spain.)
There are metric tons of coverage over the last few years about this

I'm guessing this is a variation of your story:

I mean the premise of the article definitely isn't fake. People are getting rejected for TIE cards, that's always been a thing.
Brexit now forces British expats to apply for a TIE card.
So what's left to be fake news?
For the record, most people associate fake news with stuff that's based in complete lies, not stuff that's maybe a little low quality.
That's an absurd, bad-faith generalization.
