It's not unsurprising that they would have maybe tried using similar techniques they've used before, especially if it was a mostly-inactive hobby site.
There is also the possibility they don't keep up with modern AI development at all and then this looks like any old spam that will stop in a few days (as it did).
Now whether it is wise to keep an old page which such outdated behavior online is another question.
