Thanks for the info, Caminante.
On the "About" page, there is a comment from August 27, 2021 that appears legit, and the next comment is a spambot posting on December 22, 2022. After that, it's all spam. The last real comment is on page 8 of the comment section, which now runs to 457 pages.
I wonder if someone kept the site cleaned up for a while, then it was either shut down or inaccessible until December 2022? In any case, the spambots kept dumping all over it until October 2023, when the site was down. At this point, it probably would be best to simply shut down the comment sections.
