RustHelper.com runs a close to vanilla survival server. The only mods installed are ownership remover, non craft able explosives and admin restrictions. We are adamant about preventing admin abuse and so we have restricted admin controls to only kick, ban and teleport (for people who get stuck). Otherwise, it is a vanilla survival server.
Server rules are listed on our website at: http://www.rusthelper.com/server/survival/
