Which is entirely a result of Steam abandoning any human intervention on their curation system, first by trying to crowdsource it and when that didn’t work just opening the floodgates and implementing the lightest possible moderation, social media-style.

So okay, do they want to avoid exploits? Go back to curating the library. That’s how it used to work, it didn’t need to be an automated, hands-free process.

But if you’re going to let everybody upload to it then you are on the hook for the costs of moderation. It’s not a valid excuse to charge more for the privilege of being slotted against shovelware. It’s not a viable argument at all.
