Visited twice in May 2021 (sites 54 & 39) bookending our camping roundtrip from Virginia to Kansas and this was one of the worst places we stayed. We lived in Dayton for a number of years and Yellow Springs is one of our favorite places. That being said, we were quite disappointed at the set up.
There is no privacy between campsites, at all. If someone on one end of the campground is having a party, everyone in the campground is going to be up all night (our first night). On our last night there, we (and the poor family with young kids in a tent 15 feet away) were audibly assaulted by a very amorous and inebriated couple in a tent until the wee hours. With no trees between sites, you have no buffer and good god what I would have given for a buffer.
Pit toilets have those heavy doors that help keep things less buggy (positive) but because they are on a raised area in the middle of an almost treeless campground, the clang of them shutting echoes throughout the night.
No showers.
No dedicated tent-pads. We were car-top camping so I can't speak to ground conditions for tent camping but do know our two spots would have put us on some sort of slope. (Unless we set up a tent right next to the road on 54).
Like I said, it wasn't bad. Definitely wasn't great.
