So about 6 months ago my mom stopped being friends with this 44 year old woman because she would call screaming all the time and then the next day call like everything was fine. So my mom changed her number. This nut job somehow got a hold of my email address and is now harassing me. I'm going to block her but I'm sure she will just make a new account and send me more crazy messages. Is there legally anything I can do? Like isn't this against the law or something that she's harassing my mom, my grandmother and me like this?
