Okay so this is kind of a crazy story. Details are below..

I roleplay with a group of girls (I won't name the site.. the site isn't the issue) well we found out one girl has been getting us deleted, stalking us Du can say she is obsessed with us. We have tried blocking her, confronting her about the situation, one girl even got the authorities involved.. well that was basically a dead end.. (keep in mind this girl ADMITTED to doing it then sagte she has quit) well apparently even blocking her doesn't work. I am beginning to have doubts about one of my Friends because it's still going on though she claims she isn't doing anything. I am afraid if I do confront her and she is innocent it will destroy our friendship.. what do I do?
