So 5 out of 50 of your scouts were not up to snuff, that's not bad, and you helped a lot of people in the process. But this was over the course of a year or two, right? That's a lot in a short time.
The problem I've encountered most, was comprehension, and following through on undeniably good advice... some folks have the talent, but aren't scout worthy, for lots of reasons. Maybe there's a post in Art 101 we could point them to...

How does one peruse unscouted artists?! Oh wait, only a scouted artist can do that right?
Just scrolled though your 'tree' and wow, everyone of them looks promising and serious! Remember when jiovanni first started posting, everyone was downvoting her? Do you counsel your scouted artists on making their work look more presentable, and not just a sketch on white?
Anyway congrats man, elevating your fellow man/woman is a noble task :)

Yeah only scouted artist can browse that part of the portal, the good thing is that i can still go and navigate that part, so in the end i lost nothing, and deep down i know that i wanted an excuse to not scout people, so this is working for my lazy self.
I always try to give constructive criticism both for the good and bad things, i am not one to hold back, i myself like the sketch on white aesthetic but if i see that they have a talent for coloring then i tell them to explore that side more.
