It's a remote possibility that the list o' 99 on Buzzfeed haz triggered the request:

james_nicoll posted a link to it last night.

I don't know about the trigger, but having looked at it may I suggest you dd Kate Thompson's The New Policeman (2005)?

You haven't acquired any new web links in the last month or so - last new linking domain was March 20th according to ahrefs:

Can't speak to social media, though.

It's one of the standard tools for SEO these days, including working on brand sites with large budgets, so it's almost certainly legit - but it does track small links that you might not notice come or go.

I'm very interested by your findings there - as will friends of mine who spend five or six figures a month based on Ahref's outputs be. Which sites did you check? I'll go have a look into the cliff and find out what's going on.

(Needless to say, if we discover that Ahrefs is dodgy, that's kinda important!)

I wonder whether similar lists exist for the other nations of the world.

To be fair, Planet Belgium has fewer hectares, and is also harder to mine for sense of wonder.

Wikipedia has Category:Science_fiction_by_nationality of author, but not by setting.

You got a mention on the Cedar Lounge Revolution Blog on the 10th.
I would guess that could be the reason for the flurry of interest?
