Los Drogas is a classic anarchy server where truly anything goes. Hacking, griefing, raiding, and trash-talking are all allowed, so if you want a ruthless survival world with no hand-holding, this is it. It is the kind of place where you either adapt fast or get left behind.
The community has a mix of sweaty competitive players and more laid-back people too, so there is still plenty of room for chaos and banter. The admin also runs regular events and stays active with the playerbase, which keeps things interesting even in a full anarchy setup. Good luck!
