Zomboid has (in my opinion) the best and most friendliest gaming community out there, so I don't think there will be many trolls to begin with however im not saying we don't have trolls in the community and I certainly don't want to see (when its multiplayer) zomboid to go downhill because multiplayer is based around pvp rather than survival. I place my trust in the devs that they will think of some thing to over come this but for now lets just enjoy our wubuless zomboid :3 (p.s cant wait for npcs!!)
