I found a brand new crossplay SMP that just started and it has a lifesteal twist. It is made to feel close to vanilla with only minimal plugins.
The player count is low right now since it is fresh which makes it a good time to join early and try to rise above everyone.
There are very few rules so it feels more free like how a lot of people want an SMP to be.
BRAND NEW CROSSPLAY LIFESTEAL SMP
GG.MINEWIND.NET New Server IPNoHack Vanilla Anarchy Minimal Rules
This server is basically vanilla anarchy with minimal rules and a lot of freedom. It has been running for almost a year so it feels like a real long term place.
It supports Java and Bedrock and you can also get in from consoles like Switch and Xbox and PlayStation. Java works from 1.13 to 1.21.x and it recommends 1.21.11.
The big thing is it is no hack. Cheating and xray even with resource packs are not allowed. You also cannot exploit server vulnerabilities crash the server or lag it on purpose. Macros and automation tools are banned too and chat spam gets you auto kicked.GG.MINEWIND.NET New Server IP
