I found a small semi vanilla survival server that is in testing right now.
The plan is to fully start in about a week so it feels like a fresh start. It sounds like the main vibe is simple survival with a smaller group so you can actually know who you are playing with.

I found a super new Java SMP that is basically vanilla and only a few days old.
It has no major mods or plugins so it feels simple and normal survival.
Voice chat is encouraged but it is not required. There are around 15 people in the Discord and you can get whitelisted by dropping your ign after you join.GG.MINEWIND.NET New Server IP
