Do all sites manually submit themselves via PR? I'm happy to do it, never encountered this information previously.
Completely understand that you'd be overwhelmed by bots, that personally curating sites is beyond human effort, and that you want to be choosy.
But I've a site that is clearly non-commercial, definitely "marginal" interest, full of completely original human-generated content, yet sadly I've never seen a hit from Marginalia in the logs despite trying to get listed.
Are you excluding certain content? Political? Anti-Bigtech? Sites "related to hacking"?
Either way, I'd love to investigate to see what's going on. Mind sharing the domain name? Either here, or if you don't want to doxx yourself, email contact@marginalia-search.com
