I'm glad that Valve isn't intervening so much and allows the publication as if it was their own website. We don't want Valve to decide what slop is and what not, it shouldn't be Valves decision. You don't want to give Valve this power. Instead, inform the user, and let each of them decide for themselves if they want it or not.

The better choice would be to ignore people who childishly refer to games people create as "slop" because they are upset by how good the tools used are. I think they'll get there eventually, but right now it's popular to hate AI. All the cool kids are doing it; especially the bullies.
