The relevant JS is:

   setInterval(function() {
     fetch("https://gyrovague.com/?s=" + Math.round(new Date().getTime() % 10000000), {
       referrerPolicy: "no-referrer",
       mode: "no-cors"
     });
   }, 300);

So perhaps this is some kind of revenge/DOS attack attempt/deliberately wasting their bandwidth in response to this article? Maybe an attempt to silence them and force to delete their article? But if it is, then I have so many questions. Like, why would the owner of the archive do that 2.5 years after the article was published? Or why would they even do that in the first place, do they not know about Streisand effect?

I'm confused.
