so i have 2 xpgrinders in my village that say for villagers to use only and ive noticed a few times random people are in there ive never met or know, i was fine with it at first until theres 4 or 5 random kids using my xpfarms at the same time, i found they had been using the public warp id set for people in my village who couldnt set homes, i know its my own fault i should've thought it through so i was wondering does anyone know a way i can only allow people in my village to open the door or a way where only villagers can access it. i just want any ideas because its getting rediculous where me and my villagers cant use their xp grinders because some nubs take advantage of the sign.
