I found this competitive survival SMP that runs on a simple strength system. When you kill a player you gain 1 strength. When you die you lose 1 strength. Your strength shows how well you are doing so every fight feels important.
The server is hosted in EU London. It has proximity voice chat so you can hear people nearby which makes fights and meetups feel intense.
There are some clear rules like no cheating no x ray no exploits and no duping. You also cannot build bases below ground. Combat logging is not allowed and if you log out during combat you will get killed.
Ganking is allowed and traps are allowed so you have to stay alert. There is a TPA system with offline requests and villagers restock fast plus trade cycling. Combat log punishments are automatic and there is inventory rollback if it is needed.
