I agree with the sentiment that there is too much slop. Used to be I'd get a message from a noob to check their steez and you'd open up a horrific .blend file or some single huge file of uncommented nonsense code, and I'd spend the time to give them pointers, and seeing them grow as a dev was rewarding. Nowadays a noob sends you a project and it's so much further along than it has any right to be and it all looks amazing and extremely sloppy and I feel like they're just wasting my time. What's the point of me critiquing the output of AI? You're just going to feed my critique into the AI some more and let it run. There's no learning or progression here.
I would like to see a version of itch.io where you _have_ to post the source code.
I also disagree with your $100 deposit idea. That won't soothe your chafe it will just change the entire schtick of this site. For me, itch is a place to chuck MVP's and prototypes while you learn and discover with the eventual goal of releasing a "real" game on a "real" platform. I don't see making any money through itch being a sensible goal, so the $100 would just make me go somewhere else to post my garbage games.
EDIT: As the posters above have alluded to, human curation is the only real answer here. You can already create your own collections so maybe find a set of devs who are curating good non-sloppy games and follow them (or do that yourself)
We also need a way to call out and shame slop to make it less socially acceptable to waste everyones time anyone want to build slopshame.com?
