An effective way to deal with this is that a moderator who refuses to moderate the server properly will get their server delisted, and thus will not appear on the server list. Basically, you can be a racist asshole, but your server will not appear on the list, instead you'll have to type in the IP manually.

It would be nice to have an undo feature.

Well, it would be hard to add a bajillion sprites for each thing you wanted, but it would be possible to use sprite color palettes. RCT does this already for its vehicle sprites. For things like hats and hair, it would be more efficient to have these as seperate sprites superimposed on the peep's head, so you don't have to have a sprite for every possible hat. If you wanted to get crazy with things, you could use a sort of character customizer with the game choosing random features, sorta like the Mii Channel. I know that's how Planet Coaster makes its peeps so diverse, as well as make your avatar. The game stores these as simple data that it can model and render on-the fly. But keep in mind, Planet Coaster is a 3D game with a free-flying camera fully 3D assets rendered in 3-point perspective developed in the mid-2010s while RCT is a game developed in the late 90s with a limited resolution locked in four isometric camera views that allow for a more coherent blend of 3D models and 2D sprites. Diversity was harder to include in older games due to the limited resources. It's certainly not impossible, as Madden '95 managed to get 16-bit consoles to do it, but it can't be an afterthought. I'd be excited to see what you do with this, however!

I still have this issue in the new version.
