My mtg site is kind of one of those. I use a static site generator, but I wrote the html templates and CSS myself to match the aesthetic I wanted.

I have robots.txt configured to keep it mostly unmolested, but I don't think it's fully unindexed.

That said, it's not very evocative of 90s web style. I do not miss those days (despite being the owner of a webhosting/design company at the time).
