Dealing with a threating character

I am unsure about were to place stuff in here so bare with. But anyways I get passed up in El Nath by this person who found out my personal info. Character name Demoiish in the Bera Server, the person ran into me and said my whole name, then says my husband is fat and found out who he is, and also found out my city of location. My husband goes to whisper him and then he threatens to have both our maple accounts remote hacked and now I dont know what to do. I need some advice. Please can anyone help me. This is freaking me out
