They are being obnoxious to get a response from other players … your choice how you react … Server 1312 is a PvP server … so blow it out of the sky … make the players a “kill on sight” target … spoil their fun by making sure they can’t do what they want to do - block access to their bases - kill their pets - kill their thralls - stalk them when online to ensure they can’t gather, that they can’t get back to their bases unharassed, ensure they can’t raid other people without harassment - kite world bosses onto them OR completely ignore them ie don’t touch their buildings; don’t engage them in pvp one-on-one … and if they try more direct attention-seeking behaviour (eg typed, voice, further obnoxious signs) then ignore … don’t even stop to tell them how pathetic they are…
