IMO {{Listed Invalid ISBN}} https://www.wikidata.org/wiki/Q7611261 should only ever be added by a human, and hopefully a bibliophile, as "listed" means it appeared in print on the physical item if it had a physical item, or nearest equivalent for born-digital items. fwiw, I created that template 8 years ago; how time flies. Interesting to see it now has 650+ uses on en.wp, and has been translated into 14 other languages. ;-)
