I found Malgazar SMP and it is a chill survival server where people are not supposed to ruin your builds. The community is pretty active and it is mostly friendly even if there are a few toxic people sometimes.
It is hosted in the UK and it runs on Purpur. It is for official Minecraft launchers only so no cracked clients.
The rules are focused on being safe and fair. No griefing no stealing no scamming no slurs no drama and no cheats like x ray or seed maps. PvP is only if both people agree and you also cannot mess with other peoples pets or animals. If you break rules you can get locked in a cage for some time or get banned.
Keep inventory is on and explosions do not destroy blocks. There is veinminer and mcMMO rankings for stuff like mining and sword. Fishing loot is boosted with tiny chances for rare items. The world border is set to 15k and the outer End islands reset every week. There is also a mod that can undo grief fast and show who touched a block.
People often live near the hub around -1k -1k and the usual online count is around 7 or more with about 470 overall players mentioned.
