Mystery Person asking to be my friend

So I just got done raping some kids as Leona when I got a friend request from someone named Permora. Now, I have never played with this person before and none of my friends have either. Op.gg and Lolking both say this person doesn't even exist on the NA servers. I didn't even accept this person's invite when I got a message from then asking for my email (wtf?). It also says this person isn't online but the chat room is colored like it is if that person is online. On my friends list now if I look for this person's name it's black instead of white.

Edit: This person is off my friends list (I guess he/she removed me).
