My old friend is threatening to come to my house and hacked into all of my social media accounts & my sister's.
My ex-friend that used to be jealous of me hacking into my Roblox, Snapchat, and Pinterest, so it wasn't my mom (sorry mother). she's also threatening to fight me and is saying my address which i have no idea how she knows my address since i moved since i was friends with her and never told her it. She hacked into my Roblox account and changed my display name, changed my avatar, and started messaging my friends on there. She did the same with my Pinterest but is typing inappropriate things in the search bar, like: "naked (character that was in my Pinterest board)", etc. She also told us that she knew both of our names and where we lived and was communicating with us through the Pinterest and Snapchat texting thingy, and was also cursing at us. That's when she said my address, which I have no idea how she got THAT because I hadn't told any of my friends from before I moved my address. But we were arguing after I left that school district because she had been making fun of me, but after that, I had her blocked on mostly everything. So I have no idea how she got access to all of my accounts. I also don't know if it's her, or someone's posing as her because they did say all of my old friends names and knew some stuff about me. What do I do?
