> Of course, only the beeping Internet Archive totally ignored it and scraped my site. And now, despite me trying many times, they won't remove it.

Try using robots.txt to get it removed or excluded from The Internet Archive. The organization went back and forth on respecting robots.txt a couple of times, but it started respecting it (again) some years ago.

Several years ago I was also frustrated by its refusal to remove some content taken from a site I owned, but later the change to follow robots.txt was implemented (and my site was removed).

The FAQ has more information on how this works (there may be caveats). [1]
