On a more serious note, I wonder how many thousands of other purely fun sites that offer no useful service have been forever lost. Hosting requires periodic maintenance (e.g. hosting fee payments, domain name renewals, SSL certificate updates). I bet a lot of sites like this disappear after a year or two when their creators either forget about them or are unwilling to continue maintaining them.
Due to this specific site’s dynamic nature, it cannot be captured by the Internet Archive. When it’s gone, it’s gone.
