Ha, awesome, thank you guys! That puts my mind at ease at least that I'm not ill-advising anyone if I put a stop to any fully illustrated books intended for publishers.
@Melissa_Bailey I'll keep that in mind about dummy books in future too. I think a lot of authors just want to hold something in hand that gives them THEIR vision and they're just excited to jump in. Sketches, I can fortunately offer at a prize that I feel won't be a major loss to them if they do think it's right for them, but I'll be sure to advise in future that really no illustrations is the best approach for an author intending to inquire with publishers.
I like the work coming my way of course, but it's too great an expense to in good conscience let anyone jump into
@NessIllustration It is baffling, but then there's sadly no shortage of authors that generally don't do much research into the publishing or self-publishing process. So many people really jump into it straight after finishing their very first story.
